2.2. Background of brain-computer interfaces

Biocompatibility and safety are the primary issues that must be solved in brain-computer interface applications. Nanomaterials, when in prolonged contact with human tissue, must ensure that they do not trigger an immune response, rejection reaction, or toxic reactions. This requires researchers to conduct in-depth research on the surface properties, chemical composition and biodegradability of nanomaterials to design nanodevices that are highly compatible with human tissues. However, due to the complexity and differences of human tissues, there are still many difficulties in achieving this goal. The long-term stability and reliability of nanotechnology in brain-computer interfaces are also urgent problems to be solved. Brain-computer interfaces need to operate stably in the human body for a long time, which requires the nanodevices to have good durability and stability, and can resist the erosion of various physical and chemical factors in living organisms. The long-term effects such as nanomaterials degradation and migration in complex physiological environments, as well as their effects on neural tissues, are not fully understood, which limits the widespread application of nanotechnology in brain-computer interfaces[4].

The precision and resolution of nanotechnology in brain-computer interfaces also face challenges. Although nanotechnology greatly reduces the size of electrodes and improves the accuracy of neural signal recording and stimulation, the close combination of electrodes and neural tissue, the stability of signal transmission and noise interference. These problems not only affect the quality of neural signals, but may also may cause damage to neural tissue. Nanotechnology also faces great challenges in the decoding and interpretation of neural signals. Neural signals are extremely complex and changeable. How to extract useful information from massive neural signals and accurately decode and interpret them is an urgent problem to be solved in the field of neuroscience and brain-computer interface. Although nanotechnology can provide high precision neural signal recording, it still needs complex algorithms and computational models in the processing, analysis and interpretation of signals, which increases the complexity and cost of the system. The ethical and legal issues of nanotechnology in brain-computer interfaces cannot be ignored. With the continuous development of brain-computer interface technology, the ethical, privacy and security issues have become increasingly prominent. How to promote the healthy development of brain-computer interface technology while protecting personal privacy and rights is an urgent problem to be solved in the current society. The application of nanotechnology in brain-computer interfaces also involves the supervision and approval of medical equipment, which needs to be regulated by perfect regulations and standards by relevant departments.

Although the innovative application of nanotechnology in neuroscience and brain-computer interfaces has great potential and prospects, it also faces many challenges in biocompatibility, safety, long-term stability, accuracy, resolution, signal decoding and interpretation, and ethics and law. In the future, with the continuous development and improvement of nanotechnology, and the deep cooperation of interdisciplinary research, we have reasonable to believe that these challenges will be gradually overcome, and that nanotechnology will play a broader and deeper role in the field of neuroscience and brain-computer interface.

In terms of the recording of neural signals, nanotechnology can be more accurately localized to single neurons or clusters of neurons with their tiny size, significantly improving the resolution and sensitivity of signal acquisition.

These nanotechnology are usually made from advanced materials such as carbon nanotubes, graphite or metal antiparticle[8]. They not only have excellent electrical conductivity, but also effectively reduce the interfacial impedance with tissues, thus increasing the efficiency of signal transmission. In terms of neurostimulation, the application of ministerial also shows great potential. Through precise regulation of the geometry, surface charge and material composition of nanotechnology, more precise and low-energy nerve stimulation can be achieved, which is of great significance for the treatment of neurodegenerative diseases and promoting nerve regeneration. Antimalarial have also been used to build intelligent neural interfaces that can respond to specific neural activity patterns, realize dynamic regulation and adaptive stimulation, and further improve the functional and intelligent level of neural interfaces. It is worth noting that the application of ministerial in neural interfaces also needs to consider key factors such as biocompatibility and long-term stability. Therefore, researchers are working on the development of ministerial with excellent biocompatibility, such as surface modification, functionalization modification and other means, to reduce the immunogenicity and toxicity of materials, to ensure their long-term safe use in the body. Meanwhile, evaluating the long-term stability of ministerial in neural interfaces, including the degradation, migration and biosafety of materials in complex physiological environments, is also the focus of current research.

The versatility of ministerial also brings new possibilities for neural signal recording, for example, through surface modification or functionalization, nanotechnology can achieve selective detection of specific neurotransmitters or ions, providing richer information for neuroscience research. In neurostimulation, nanotechnology also shows great potential. Using the unique properties of ministerial, such as photosensitivity, electronegativity or magnetic responsiveness, more accurate and low-energy neurostimulation strategies can be designed. These nonreticulateare able to respond to external signals, such as light, electricity or magnetic fields, to achieve precise stimulation of specific neurons or clusters of neurons, thereby modulating neural activity and promoting the recovery or improvement of neural function. The combination of cytogenetics with nanotechnology makes it possible to stimulate neurons with the expression of specific genes through light, providing a powerful tool for neuroscience research[9]. The small size and biocompatibility of the nonreticulate also offer broad prospects for their application in the treatment of chronic neurological diseases, such as Parkinson's disease, epilepsy, etc. It is worth noting that the application of nanotechnology in neural signal recording and stimulation still needs to solve some challenges, such as long-term stability, biocompatibility and safety. Through surface modification, material optimization and other means, decrease the immune response and toxicity, to ensure its long-term safe use in the body. The evaluation of the long-term effects of nanotechnology in neural interfaces, including the stability of materials in complex physiological environments, and the effects on neural tissues, is also the focus of current research.

By precisely controlling the size, shape and surface properties of materials, nanotechnology has designed ministerial that are highly compatible with nerve cells, which show significant advantages in promoting nerve regeneration, guiding axon growth and accelerating nerve repair. On the one hand, noncommercial can serve as a "bridge" for nerve regeneration, providing physical support and guidance for the growth of nerve cells by building three-dimensional nanocephalic. These nanocephalic are usually made of biocompatible materials, such as polylactate-hydroxyacetate copolymer (PLGA), collagen or hypertonic acid, which can mimic the microenvironment of neural tissue and promote the migration, differentiation and axonal extension of nerve cells. By adjusting the pore size, shape and arrangement of the nanosecond, the growth direction of nerve cells can be accurately controlled, and the precise repair of nerve tissue can be realized. On the other hand, noncommercial can also further promote nerve regeneration by releasing bioactive molecules such as nerve growth factors and cytokines. These molecules play an essential role in neural development and repair processes, and are able to stimulate nerve cell proliferation, differentiation, and synapse formation. Through nanotechnology, these bioactive molecules can be loaded onto antiparticle or magnifiers, enabling their precise delivery and sustained release in neural tissue. This not only increases the efficiency of biomolecule utilization, but also reduces the side effects of systemic administration. Nanotechnology can also promote nerve repair by modulating the microenvironment of nerve cells.

For example, using the optical, electrical or magnetic properties of ministerial, the precise regulation of neural cell activity can promote the regeneration and functional recovery of damaged nerves. Antimalarial can also be used as drug carriers to deliver neuroprotective agents, anti-inflammatory drugs and other drugs to the damaged sites, reducing the inflammatory response, and promoting the repair of nerve tissue. It is useful to noting that the application of nanotechnology in nerve regeneration and repair also needs to focus on biocompatibility, safety and long-term effects. Therefore, efforts are being made to develop safer and more efficient ministerial to reduce the immune response and toxicity through surface modification and functionalization to ensure their long-term safe use in the body.
