With the development of science and technology, materials science and biomedicine are combined more and more closely, nanomaterials in biological applications have made great achievements and show good momentum and great potential for development. However, we should also see that many aspects of the development is not perfect, the application is not safe for further research. The author believes that in the 21st century, the development of nanomaterials in biomedicine should be strengthened and have great potential for application, will become a hot spot for research in the coming period of time:
(1) biomedical testing and diagnostic materials: it is undeniable that the nanomaterials in the diagnostic bio-detection has been considerable development and application of a variety of nanomaterials have been applied in practice to achieve good results. However, the requirements for various functional nanomaterials in various medical tests are still relatively high. For example, biomedical engineering and medical equipment and equipment complement each other, biomedical engineering is the basis of its subject of research in-depth will give rise to new medical equipment and equipment, while the demand for clinical medical equipment and equipment information will produce new research direction, nanofunctional materials in this area will have a great future. Another example is the further optimization of analysis and detection technology, which will inevitably require the emergence of nanomaterials with more advanced performance.
(2) materials used in drug therapy: drug-controlled release nanomaterials will continue to be the focus of nanomedical materials research and development. Nanoparticles not only have the ability to pass through the tissue gap and be absorbed by the cells and other characteristics, but also has the target, slow release, high efficiency, low toxicity and can be achieved orally, intravenously and dressing a variety of routes of drug delivery and other advantages, and therefore has a broad application prospects in drug delivery.
(3) functional biomaterials: a variety of materials with specific functions will be increasingly used in biomedicine up. In the next few years, nanoceramics in biomaterials will play a leading role in artificial bones, with a variety of characteristics of inorganic - organic composite nanomaterials will also be in the interventional therapy, blood purification to play a big role.
(4) Bio-safety nanomaterials: At present, the safety research of bio-nanomaterials in some countries has been put on the agenda, but a lot of research is not in-depth, and the results are not obvious. In the global attention to safety issues at the same time, nanomaterials safety research will certainly become the next hot spot. Biodegradable green materials will be the first choice for future drugs. Regarding the risks of biotechnology, there are indeed still many questions that have not been clarified and need to be continued research.
The combination of nanotechnology and biomedicine has provided the medical community with brand new ideas, and the application of nanomaterials in the medical field has achieved remarkable results. However, the application of nanomaterials is still very limited, especially in biomedicine, most of the research is still in the stage of animal experiments, and a large number of clinical trials to be confirmed, and the biosafety of nanomaterials application needs to be further improved. This requires biomedical researchers and nanomaterials researchers to further strengthen the cooperation to produce more advanced biomedical nanomaterials. We have reason to believe that, with the wider application of nanomaterials in biomedical field, the clinical medical treatment will become faster pace, higher efficiency, more accurate diagnosis and examination, more effective treatment, and the safety of people's lives will be more secure.
