“`html

In 2025, China is positioning itself as a global leader in cutting-edge technologies, and biocomputers, which merge biology and computing, embody one of the most fascinating advances of this era. These innovative systems, integrating biological components such as brain organoids or DNA molecules, promise to revolutionize computing, robotics, cybersecurity, and even medicine. Unlike traditional silicon-based computers, biocomputers exploit the unique capabilities of living systems, such as rapid learning and energy efficiency.

What is a biocomputer?

A biocomputer is a computing system that uses biological components, such as cells, proteins, or DNA molecules, to perform calculations or process information. Unlike classical computers, which rely on silicon chips and electronic circuits, biocomputers draw inspiration from biological processes, such as neural communication or molecular interactions. Here are the main characteristics of biocomputers:

• Energy efficiency : Biological systems, like human neurons, consume far less energy than traditional processors. For example, a human brain operates on approximately 20 watts, compared to hundreds of watts for a supercomputer.
• Learning capacity : Biocomputers, particularly those based on brain organoids, can learn and adapt quickly, often surpassing classical artificial intelligence (AI) algorithms.
• Miniaturization : Biological components, such as DNA, allow the creation of extremely compact systems, ideal for applications in restricted environments.

In China, biocomputers come in two major categories: brain-chip interfaces (based on brain organoids) and DNA computers (using DNA molecules for computing). These technologies, still in their infancy, are already at the heart of ambitious projects.

Recent advances in biocomputers in China

Brain-chip interfaces: MetaBOC and robotics

One of the most spectacular advances in China concerns brain-chip interfaces, which integrate human brain organoids with electronic chips. The MetaBOC project, developed by researchers from Tianjin University and the Southern University of Science and Technology, illustrates this potential. According to an article published on Trust My Science, MetaBOC is an interface that allows neurons cultured in vitro to receive, interpret, and respond to electrical signals, thereby controlling humanoid robots.

How does MetaBOC work?

MetaBOC combines two key elements:

1. Brain organoids : These are three-dimensional clusters of brain cells derived from human pluripotent stem cells. Unlike two-dimensional cell cultures, these organoids form complex neural connections, mimicking certain functions of the human brain.
2. Silicon chip : Equipped with electrodes, the chip transmits electrical signals to the organoids and records their responses, creating a bidirectional interface.

To improve the reactivity of organoids, researchers use low-intensity ultrasound to stimulate their development, promoting the formation of neural networks. This approach allows organoids to control robotic tasks, such as obstacle avoidance or object manipulation. According to Trust My Science, these biocomputers consume far less energy than artificial neural networks and learn faster, offering a significant advantage for robotics.

Potential applications

• Advanced robotics : Robots equipped with MetaBOC could accomplish complex tasks autonomously, such as navigation in unpredictable environments.
• Medicine : Brain organoids could be used to repair brain injuries, as ultrasonic stimulation improves neural cell proliferation.
• Neurological research : These systems enable the study of human neuron function under controlled conditions.

Open-source and accessibility

The MetaBOC team plans to develop open-source software to facilitate the integration of this interface with other electronic devices. According to the researchers, it is the “first open-source complex intelligent brain-on-chip information interaction system in the world” . This approach could democratize access to this technology, stimulating global innovation.

DNA computers: A new frontier in computing

In parallel, China is making significant progress in DNA computers, which use DNA molecules to perform calculations. In 2023, Chinese scientists achieved a milestone by developing a programmable DNA-based computing unit, as reported by Bio_comunidad on X. This technology harnesses DNA’s ability to store and process information at a molecular scale.

Operating principle

DNA computers are based on the chemical properties of DNA:

• Storage : A single gram of DNA can store up to 215 petabytes of data, far surpassing the capabilities of traditional hard drives.
• Computing : Interactions between DNA strands (such as hybridization) can be programmed to solve mathematical or logical problems.
• Parallelism : DNA chemical reactions occur simultaneously, enabling massively parallel processing.

The unit developed by Chinese researchers uses “DNA arrays” to execute programmable calculations, paving the way for applications in bioinformatics and cryptography.

Potential applications

• Bioinformatics : DNA computers could analyze genomic sequences at unprecedented speeds, accelerating genetic research.
• Cryptography : Their ability to process complex data could revolutionize information security.
• Personalized medicine : By integrating DNA calculations into medical devices, it would be possible to diagnose diseases in real time.

Micro-computers for cybersecurity

In December 2024, China unveiled a micro-computer the size of a coin, 100 times more powerful than standard models, designed to strengthen cybersecurity . While this device is not explicitly described as a biocomputer, its development is part of an innovation strategy that includes biocompatible materials and miniaturization techniques inspired by biological systems.

Characteristics

• Power : Capable of processing massive data volumes in real time, ideal for detecting and neutralizing cyber threats.
• Miniaturization : Its reduced size allows integration into various systems, from household appliances to critical infrastructure.
• Energy efficiency : Uses innovative materials to optimize heat dissipation and reduce energy consumption.

This micro-computer reflects China’s determination to dominate cutting-edge technologies, combining biological and electronic approaches to address modern challenges.

Context and drivers of development in China

Massive R&D investments

China has invested massively in research and development (R&D), representing approximately 22% of international patents in 2019, according to PMC. These investments support programs such as the 14th Five-Year Plan (2021-2025), which emphasizes biotechnology, AI, and quantum computing. Biocomputers benefit from this ecosystem, with institutions such as the University of Science and Technology of China (USTC) playing a key role.

Return of talent

Since 1978, more than 4.23 million young Chinese trained abroad (primarily in North America, Europe, and Japan) have returned to China, occupying key positions in research and industry . This return of talent has strengthened China’s capacity to innovate in fields such as bioinformatics and brain-chip interfaces.

Technological infrastructure

China has one of the world’s best 4G/5G infrastructures and ranks second for supercomputers . These technologies support the big data processing required for biocomputers, particularly in bioinformatics and healthcare.

Strategy for technological autonomy

China seeks to reduce its dependence on foreign technologies, particularly American ones. Initiatives such as replacing 50 million foreign PCs in government administration with local alternatives reflect this ambition. Biocomputers, as innovative technology, fit into this quest for autonomy.

Comparison with global technologies

Chinese biocomputers stand out through their hybrid approach, combining biology and electronics. Here is a comparison with other global initiatives:

China stands out by integrating its biocomputers into practical applications, such as robotics, and through its open-source approach, which contrasts with more compartmentalized projects elsewhere.

Ethical implications and challenges

Ethical questions

Biocomputers, particularly those using brain organoids, raise major ethical concerns:

• Organoid consciousness : Although organoids are not conscious, their increasing complexity raises the question of their ethical status.
• Consent : The use of human stem cells requires strict protocols to ensure informed consent.
• Surveillance : In a country like China, known for digital surveillance, the integration of biocomputers into critical systems could amplify privacy risks .

Technical challenges

• Reliability : Biological systems are sensitive to environmental variations, which can affect their stability.
• Scalability : Transitioning from laboratory experiments to large-scale production remains a challenge.
• Regulation : The absence of global regulatory frameworks for biocomputers complicates their adoption.

Environmental impact

Although biocomputers are more energy-efficient, their production (particularly organoid culture) requires significant resources. China, which faces major environmental challenges, will need to balance these needs with its sustainability objectives .

Future perspectives

Chinese biocomputers could redefine several sectors by 2030:

• Healthcare : By combining biocomputers and AI, China could accelerate diagnostics and personalized treatments.
• Cybersecurity : Bio-inspired micro-computers could offer robust defenses against cyberattacks.
• Education and research : MetaBOC’s open-source approach could stimulate global collaboration, strengthening China’s position as an innovation hub.

However, the success of these technologies will depend on China’s ability to address ethical concerns and establish international standards. Partnerships with institutions such as the WHO or UNESCO could help legitimize these advances.

Biocomputers in China represent a bold convergence of biology, computing, and engineering. Projects such as MetaBOC and DNA computers illustrate the potential of this technology to transform robotics, healthcare, and cybersecurity, while strengthening China’s technological autonomy. However, ethical, technical, and environmental challenges require a careful and collaborative approach. In 2025, China is not merely following global trends; it is redefining them, laying the foundation for a future where the boundaries between the living and the machine blur.
