From gene sequencers in laboratories to CAR-T cell therapies in hospitals, from insect resistant genetically modified crops in farmland to microbial degradation technology in sewage treatment plants, biotechnology is infiltrating every corner of human production and life in a "subtle and silent" way. The global biotechnology market is expected to exceed 800 billion US dollars by 2025, and the scale of related industries in China will also reach 6 trillion yuan. This technological revolution centered on "life sciences" is not only cracking the code of life, but also reshaping the infinite possibilities of future life.

1、 Medical and Health: A Paradigm Innovation from "Treating Diseases Already" to "Preventing Diseases Before They Occur"

The subversion of biotechnology in the field of healthcare is first reflected in the fundamental transformation of disease diagnosis and treatment models. In the field of precision medicine, the cost of gene sequencing technology has dropped from $3 billion per person in 2001 to $100 per person today, making personalized treatment tailored to each individual a reality. At the beginning of 2025, a domestic biotechnology company launched the "whole exome+methylation" joint testing package, which can screen more than 1200 single gene genetic diseases and more than 20 cancer susceptibility genes at once, achieving breakthroughs in newborn screening and early tumor screening. Currently, it has been applied in more than 300 hospitals across the country, with a total of over 500000 people tested.

Cell and gene therapy (CGT) has become a powerful tool for overcoming difficult and complicated diseases. As of March 2025, there are 38 approved CGT products worldwide, among which China's independently developed "CAR-T cell injection targeting CD19" has an objective response rate (ORR) of 92.3% and a median progression free survival (PFS) of 34.6 months in the treatment of relapsed and refractory large B-cell lymphoma. The related technology has been exported to 12 countries and regions including the European Union and Japan. More noteworthy is the breakthrough in "in vivo gene editing" technology - the AAV vector gene editing system developed by the Chinese Academy of Sciences team can directly repair pathogenic genes in the liver through intravenous injection, successfully curing hereditary hemophilia in mice. This achievement was selected as one of the "Top Ten Breakthroughs of the Year" in Nature Biotechnology in 2025, opening up a new path for the treatment of rare diseases.

In the field of preventive medicine, the application boundaries of mRNA technology continue to expand. Following COVID-19 vaccine, the "herpes zoster mRNA vaccine" developed by domestic enterprises was approved for marketing in April 2025, with a protective effect of 97.2%, and the incidence of adverse reactions to people over 50 years old was only 1/3 of that of traditional vaccines; The preventive mRNA vaccine for Alzheimer's disease has also entered phase II clinical trials, and by targeting the deposition of A β protein, it is expected to reduce the risk of disease occurrence from the source. These breakthroughs mark the transformation of healthcare from "disease treatment" to "health management", with biotechnology becoming the "first line of defense" for safeguarding life and health.

2、 Agriculture and food: solving the problem of "food security" and reconstructing the supply system

The challenges of "food security" brought about by global population growth and climate change are being solved through biotechnology. In the field of crop breeding, the application of gene editing technology makes "precision improvement" possible. In 2025, China's independently developed "insect resistant and herbicide resistant corn" has been approved. By editing the ZmCCoAOMT2 gene, this variety not only has a resistance rate of 96% against corn borers, but also can tolerate glyphosate herbicides without introducing exogenous genes, and its safety is no different from traditional breeding varieties. At present, this variety has been promoted and planted on 15 million acres in Northeast China and the Huang Huai Hai region. Each acre can reduce pesticide use by 30% and increase production by 15% -20%. Based on this scale, it can produce about 3 billion kilograms of grain annually, equivalent to the annual food supply of 3 million people.

Microbial technology provides a new solution for the green development of agriculture. The "nitrogen fixing cyanobacteria bacterial agent" developed by a certain biotechnology company can convert nitrogen in the air into usable ammonia nitrogen by symbiotic with wheat and rice roots. It can reduce fertilizer use by 40% per acre, improve soil structure, and increase soil organic matter content. This technology has been promoted and applied in 8 million acres of the Yangtze River Basin, not only reducing agricultural non-point source pollution, but also increasing the average yield of rice by 8% -12% per acre. In the field of livestock and poultry breeding, the technology of "probiotics replacing antibiotics" has become a trend - through screening lactic acid bacteria strains with antibacterial activity, the developed probiotics preparation for livestock and poultry can reduce the incidence rate of broilers by 25%, reduce the use of antibiotics by 90%, and increase the content of egg white in chicken by 1.5 percentage points, realizing a win-win situation of "safe breeding" and "quality improvement".

In the field of food, breakthroughs in synthetic biology are restructuring the food supply system. In 2025, the first domestically produced "cell cultured beef" will officially enter the market. This product extracts stem cells from cow muscle and cultivates and differentiates them into muscle tissue in a bioreactor. The production process does not require breeding cattle, reducing 90% of land occupation, 80% of water resource consumption, and 70% of carbon emissions. It also does not contain antibiotics and hormones, and has a protein content 12% higher than traditional beef. At present, the product has been launched in more than 200 restaurants in cities such as Beijing, Shanghai, Guangzhou, and Shenzhen, with monthly sales exceeding 50 tons; In addition, the "PHA degradable packaging material" produced through synthetic biology technology has also been applied on a large scale, replacing traditional plastic packaging and completely degrading in the natural environment within 180 days, providing a biological solution to solve "white pollution".

3、 Environmental Protection and Energy: Activating "Biokinetic Energy" to Support Sustainable Development

Driven by the "dual carbon" goal, biotechnology has become a core force in promoting environmental protection and energy transformation. In the field of pollution control, microbial degradation technology has demonstrated unique advantages. In response to the challenge of chemical wastewater treatment, a research team has identified the "Pseudomonas J-1 strain", which can reduce the phenol concentration in wastewater from 1000mg/L to below 0.5mg/L within 72 hours at 30 ℃, with a degradation rate of 99.95%. Currently, this technology has been applied in more than 20 chemical parks across the country, and can treat over 5 million tons of high concentration organic wastewater annually, reducing COD emissions by about 30000 tons. In the field of soil remediation, the "fungus plant joint remediation technology" has become mainstream - by inoculating arbuscular mycorrhizal fungi with heavy metal adsorption ability and combining them with hyperaccumulating plants such as centipede grass, the cadmium and lead content in the soil can be reduced by 60% -80%. This technology has been applied in the remediation of 2 million mu of heavy metal polluted farmland in Hunan, Guangdong and other areas, making the polluted soil meet the standards for crop planting again.

In the field of renewable energy, the industrialization process of biofuels is accelerating. In 2025, China's first "microalgae biodiesel" production base will be put into operation in Shandong. The base will cultivate high oil microalgae on a large scale, extract oil using biotechnology, and convert it into biodiesel. The annual output will reach 100000 tons, which can reduce carbon emissions by 65% compared to traditional fossil diesel. More groundbreaking is the cost breakthrough achieved by the "cellulose ethanol" technology - through genetically modified brewing yeast strains, agricultural waste such as corn stover and wheat bran can be directly fermented to produce ethanol, reducing the production cost per ton of ethanol to less than 3000 yuan, only 60% of traditional grain ethanol. Currently, this technology has built five production bases in Henan, Heilongjiang and other places, which can digest more than 2 million tons of agricultural waste annually and produce 500000 tons of ethanol, providing a new path for the development of renewable energy that "does not compete with people for food and land".

4、 Challenge and Prospect: Moving towards the Future through Innovation and Standardization

Despite the rapid development of biotechnology, it still faces many challenges: at the technical level, scientific issues such as off target effects of gene editing and the long-term safety of cell therapy still need to be overcome; At the industrial level, the production cost of CGT products remains high, and some core equipment and reagents still rely on imports; At the ethical and regulatory level, there is still a need to establish a sound regulatory system for the application boundaries of gene editing in the field of human reproduction and environmental risk assessment of synthetic biology products.

Looking ahead to the future, the development of biotechnology will present three major trends: firstly, the acceleration of interdisciplinary integration, where the combination of artificial intelligence and bioinformatics will increase the efficiency of gene sequencing and drug development by more than 10 times; The second is the deepening of industrial applications. Technologies such as cell therapy and synthetic biology will move from "niche markets" to "mass applications". It is expected that by 2030, the global biotechnology market will exceed $2 trillion; The third is to strengthen global cooperation. In the face of global challenges such as infectious disease prevention and control, food security, etc., international cooperation in the field of biotechnology will become mainstream, and China is expected to occupy an international leading position in gene editing, microbiological technology, and other fields.

From cracking the code of life to safeguarding our planet, biotechnology is becoming a core force driving human social progress with its unique "life empowerment" ability. In the balance between innovation and standardization, this technological revolution will continue to bring a healthy, safe, and sustainable future to humanity, and China will also move from a "biotechnology power" to a "biotechnology powerhouse" in this process, contributing Chinese wisdom and solutions to the global development of biotechnology.
