Bionic molecule of system it assembles to be chemistry and physics, biology, and material learn cross a research focus of field, the idea of molecule bionic becomes a front line science problem which international scientific and technological circles generally pay close attention to in recent years. Attend Israel held in Beijing a few days ago " Molecule bionic " Point out for the expert of the 387th Fragrant Hills scientific meeting of the theme, molecule bionic explore biological the intersection of world and secret, new material formate with new the intersection of function and the intersection of reseach of device,etc. and respect playing an important role in mankind.

The molecule motor is worth expecting

In organism and life, equipment of since the different levels that the biological member passes, from microcosmic to macroscopic, have formed the complicated and accurate structural system of many stages spontaneously, have realized various specific biological functions. Executive chairman, chemistry high cypress researcher Li of Chinese Academy of Sciences introduce while commenting the report the meeting in the theme entitled molecule bionic, molecule bionic regards artificial synthesis molecule or biological base yuan as the research object, assemble or prepare new material and new system of structure and function bionic at the molecule level, structure and alternative, penetrating, biological molecule or his analog's detection and synthetic, etc of the function, biomembrane of the albumen in research and simulation organism. Molecule bionic can imitate the organism and realize multi-functional integrating and related, prepare intellectual material or the intersection of molecule and machine, may bionic realize the inclusive and biological function of living beings too, prepare medical material of living beings and device, has offered the limitless innovative development space for development of modern material science, especially new material of living beings.

The biological member's motor is a biological macromolecule that can turn chemical energy into mechanics. These macromolecules exist in cells extensively, they are protein, it can be DNA too, often in nanometer yardstick, is called " nanometer machine " too ,ATP synthase distributed in the mitochondrial membrane is considered to be a kind of minimum rotation molecule motors up until now.

The little nanotechnology research center Professor He Qiang of polytechnical university in Harbin introduces, ATP synthase that will be separated from the organism is recombinated on little capsule of bionic, not merely can realize the active albumen in the external recombination, reproduce ATP synthetic biological course in the organism, understand the active albumen function better, help people to imitate the function of since equipment, discern and transmit across the material of the membraning etc. of the organism at the same time, develop corresponding the intersection of function and material and device, new the intersection of bionic and material, the intersection of medicine and to transport and control, release carrier,etc. target.

Tsing-Hua University Sui SenFang Professor recommend living beings three-dimensional electron study progress and meaning in the intersection of member and the intersection of bionic and field in this respect while being micro-. Sui SenFang says, equipment from the equipment system and inferior cell structure further formed by them to the biological macromolecule on more complicated systematic level, the research of structure and function has already become one of the focuses of modern biological study.

Meeting executive chairman, the intersection of Tsing-Hua University and Liu DongSheng Professor point out core sour member should quantitative the intersection of research and the intersection of core and sour the intersection of member and course of doing work of motor in focus in the intersection of motor and future research, announce the energy under nanometer yardstick transforms the law, prepare the intellectual material in the medical field of living beings, at the same time at for studying protein molecule /among last tool interaction.

The membrane of bionic prepares and still faces a great deal of challenges

Cells are the elementary cell which make up the human body and organism, the cell membrane has its particular composition, structure and function, decisive for biological activity and function of cells. Through carrying on scientific imitation and making to the material, structure and function of the cell membrane " The membrane of bionic " ,It will be expected to create chemistry, biological physics, the new concepts and technology of biochemistry, medical science and pharmacy. Meeting executive chairman, China scientific the intersection of president and spring the intersection of applied chemistry and deep and vast research institute the health researcher says, further announce the secret of the natural biomembrane, more fully understand and know its mechanism of life, have important directive significance in solving medical science, agriculture and practical problem industrially.

Li JunBai introduces, the research of the membrane of bionic is to fully understand and know composition, structure and function of the biomembrane, especially on the structure of body of phosphorus ester, lipid and albumen and combination and foundation of the function, design and produce and make up the bionic membrane system with similar structure with it, imitate information transmission and recognition function of the biomembrane.

Research institute researcher Zhang Xin of the course project of Chinese Academy of Sciences points out, the bionic membrane structural material can be controlled and still faced a great deal of challenges fully, including the size and control of one, structure simulation, more complicated bionic membrane and design, adjustment, scale of function of the membrane of bionic prepare the practical application of technology, equipment and bionic membrane etc.. Film of bionic can be controlled and still remained during the course of testing at present fully, develop new scale and prepare the technology and equipment and realize industrialization finally, will become one of the future developing direction.

Construct the functionalization molecule bionic system

Executive chairman, theory physical Ou, male genital researcher Zhong Can of research institute, of Chinese Academy of Sciences introduce the meeting, a lot natural with structure that assemble manually, the intersection of virus and the intersection of clothing and shell, protein assemble body and the intersection of DNA and polymer, and surfactant assemble body can form 20 of body structure, 20 pieces of body are possessing minimum elasticity energy as to other straight polyhedrons, it is the most steady symmetrical structure of polyhedron. This discovery, to knowing assembling forming mechanism and mechanics property of the body, and assemble construction and functionalization of the body newlying has guidance functions.

Blue and green researcher Hua Fan of Ins of Chemistry,Academia Sinica thinks, the functionalization which realizes the molecule bionic system will be one of the challenges met while studying in the future.

The expert participating in the conference thinks unanimously, study the bionic system from the angle which the molecule assembles on the initial stage that still in development in the world at present, the scientist of our country is in status comparatively leading in this field at present. The molecule bionic research should serve great fields such as the energy, environment measuring, biological medicine,etc.. The focal point should pay close attention to: Put up flowing to accuse of the technical research platform a little of complicated biological system, develop construction of the active member's bionic system, expand the existing ATP synthase motor albumen system to other motor albumen systems; Set up molecule bionic equipment bodily form attitude and evolve the physical model; Develop the controlled device of new member's bionic function; Develop new molecule bionic and receive the craft a little, improves stability and reappearing of the bionic system; Develop the new technology and improve the accuracy which understands the bionic system work of molecule, launch research of domains of front such as molecule bionic nanometer machine and protein molecule bionic project,etc.,etc..

Molecule bionic offers the innovative space for constructing the new system and developing the new material of living beings
