International nanodevices can generally be divided into three categories, nanoelectronic devices, optoelectronic devices, and molecular electronic devices. Representative nanoelectronic devices are: single electron devices, tunneling devices, magnetic flux quantum devices, spin devices, etc.; representative optoelectronic devices are low-dimensional semiconductor lasers, detectors, modulators, etc.; molecular electronic devices mainly have molecular switches. And molecular logic devices. At the same time when research on nanodevices is being carried out internationally, the circuit and architecture suitable for nanodevices is also a research hotspot.
As the leading United States of nanotechnology, in 1999, the federal government proposed to the Congress the National Nanotechnology Plan of the United States. This plan places nanodevices and architectures as one of the research focuses. The plan describes the vision of nanodevices as follows: Nanotechnology will promote information technology. The hardware revolution, the significance of this revolution may be more than 30 years ago microelectronics replaced the microelectronic revolution of vacuum electronics. Representative new conceptual devices listed in this plan are: single electron devices, electron spin devices, resonant tunneling devices, quantum dots, molecular electronics, and surface emitting lasers. The European Community is not far behind in nanometer research. In 1996, the Microelectronics Advanced Research Strategy Action Plan (MELARI) was launched. In 2000, the NID was also established.
At present, the research of nanodevices in China is mainly concentrated in a number of famous institutions of higher learning and institutes of the Chinese Academy of Sciences. There is a significant gap between the research of nanoelectronics and nanodevices and the developed countries. The research groups and content are relatively dispersed, there is no overall layout, support intensity and research needs. There is a large gap between them and there is a lack of public technology platforms for in-depth research on nanodevices. The research topics have made considerable progress in nanoelectronic devices and sensors, but lack of innovation; there are not many research topics on core technologies and scientific issues. The new nanoelectronic devices are still mainly in the stage of theoretical and principle exploration. They have experimented with certain advantages of semiconductors and physics, but they have not formed systems and obtained some demonstrable results.
The research work of nanodevices in our country cannot meet the demands of developed countries due to the constraints of resources and industry. Emphasis should be placed on establishing a shared nano-processing platform, encouraging quantum-effects-based innovative device work, and strengthening circuit and system research based on new quantum devices. Basic research should have certain leapfrogging. Quantum computing and quantum communication systems can be used as the traction, focusing on new devices based on quantum effects. At the same time, some tracking research work should be properly arranged.
The development prospect of nano biopharmaceuticals and health care products equipment is wide. Kong Kaixuan, director of the technology R&D center of Beijing Weigehe Nanotechnology Co., Ltd., is a relatively easy-to-implement primary nano-industrialization of biomaterials. Generally, biomaterials are broken to the nanoscale or submicron level. In addition to packaging, there is no follow-up work. Without the need for engineering materials, nanomaterials must be prepared, composite compounded materials must be made, and the end product must be developed into a complex process.
Biomaterials are broken down to sub-micron and nanometer levels, depending on how much effective substances they contain, they can be several times to several dozen times stronger to enhance medicinal effects. In general, raw materials containing more crude fiber have less synergies and pure substances. Raw material efficiency is obvious. The principle is very simple. Due to the extremely small particle size of the preparation and production, high specific surface area, high chemical activity of the substance, and high biological activity lead to a linear increase in the drug absorption rate per unit time, leading to a straight rise in the total drug absorption rate. Its technical purpose is very simple and clear. It is broken and increased efficiency. It can be completely absorbed when it is broken down and digested. From the aspect of nutrient absorption theory, the part of the nutrient source absorbed by the body is smaller than the nanoscale particle size, but the content in the conventional food is relatively small.
One of the major achievements of nano- or sub-micron biomaterials breaking technology is that they can directly break various proteins into peptides, or break into small molecular weight proteins that can rapidly decompose into peptides in the stomach. In the past, the production of peptides was complicated. Protein separation, hydrolytic digestion, ultrafiltration recovery and other complex and costly processes. Since the crushing process is completed instantaneously and the process temperature can be all below 30°C, the biological activity of the polypeptide or small molecular weight protein material thus obtained is relatively high. The method has a simple process and a very low production cost. It also provides a technical platform for the development of various kinds of pharmaceuticals or health products using pharmacodynamic proteinaceous substances.
At present, the Weigerman company can use a crushing process with a particle size distribution of 60 to 160 for natural medicines, which are mainly characterized by biochemical components, in order to increase the chemical and biological activities to achieve a slight digestion and rapid absorption. At present, Weigee Company has trial-produced single-nose nanomedicines such as ginseng, gastrodia elata, bezoar, cinnabar, jujube kernel, and pearl, as well as Western participation in Rhodiola anti-fatigue group and Liuwei Dihuang Wan group. Trial production of seabuckthorn seeds oil-impregnated nano-ganoderma spore powder plus nano-organic selenium compound anticancer agent was also trial-produced. The content of the single-sided nano-organic selenium pellets reached 200PPM, and the toxic inorganic selenium content was lower than the safety standard.
Nano-crushing technology can be widely used in the development of nutritious foods with health care functions. For example, after a portion of the milk is treated with peptides and then homogenized with more fresh milk, it can become a peptide milk with blood pressure lowering and immune function enhancement. Soymilk, walnut milk and other plant protein milk can also be processed in the same way as unilateral or compound vegetable polypeptide milk. Polypeptide milk made from soybean bud embryos, corn germ embryos, and wheat bud embryos has health benefits. The homogenates of various fruits, vegetables, seaweeds, microalgae and fungi made by the submicron crushing process will be pure natural raw pulp beverages. They can be used not only for direct consumption, but also for brewing beverages and blending and freezing to make cold food. . (To be continued)
