The nanometer eyeball can't let the blind person regain one's sight yet
A few days ago, the media really made people extremely exited to the report of the nanometer eyeball: The nanometer eyeball can let the blind person see the excellent world; By the end of next year, the nanometer eyeball can realize industrialization. But the distance that the actual conditions may not be short from so wonderful a realm: The nanometer eyeball is only a kind of good cosmetic material at present; U.S.A. " Electronic eyes " Also can only make people see the fuzzy outline of the object at short range; The domestic nanometer eyeball is being designed at present " Electronic eyes " Circuit system, then assemble, later, should wait for animals to test with the outer cover successfully, it is expected to do human tail. The researcher thinks, should let the blind person regain one's sight, the nanometer eyeball has quite long ways to go. On December 16, as some medias of Beijing publish " the global first nanometer eyeball would be born in Rong " News behind,arouse great concern from various circles of society. Say in the report: "This kind of eyeball not only can rotate synchronously like normal human eye, can also stimulate the nerve of brain through the circuit of pulse, see the colorful world. " News is really exciting. Get used to for the job, the reporter, with the researcher immediately - --Professor Li YuBao of university of Sichuan gets in touch. December 18, fee so great some setbacks, reporter find and put through the intersection of jade and the intersection of treasure and Mobile of Professor Li. Just explained and interviewed the intention, that did not want to come was the other side's angry and worried words unexpectedly: " the fact is not so completely, hope the media comes to a halt at this point! " Too unexpected! Does the media report unureally? What intensity has research of the nanometer eyeball arrived on earth to? The reporter is made great efforts repeatedly, Professor Li YuBao agreed to give an interview at last, and hope this newspaper gives the objective report. This subject is a scientific research project that national Ministry of Education established of last year, were mainly engaged in " electronic eyes " that can be moved, can be looked at Exploratory work, belong to the international front and study the category. 38 -year-old Li Yu treasure Professor whether material study doctor this year, go abroad to study 1992, engaged in the intersection of nanometer and research of biomaterial hereafter. He before bearing this subject for research, finish one the intersection of country and " the 863 " already Project, namely adopt the intersection of nanometer and kinds of the intersection of bone and crystal and polyamide, develop one flexible Gao Qiang, mechanics inclusive to repair material with with excellent biological activity tissue, belong to domestic and foreignly and initiate. Now, these kind " nanometer compounds the active material of living beings " Been already further doing animal's experiment through national acceptance. The expert thinks, this kind of nanometer material approaches tissue in such aspects as biological activity, flexibility and intensity while appraising, in the skull in the future, vertebra, projecting cheek bone, rib, ilium, the intersection of ear and bone, phalanx, joint, the intersection of throat and support, wear leather device,etc. repair field, there is very much broad employing world. Professor Li YuBao introduces, can move, can look at " electronic eyes " Research last the most advanced one at present Study the paces. With the development at full speed of photoelectricity, the manufacture of the artificial eyeball is updating constantly at the surprising speed, from the dog eyeball that used first, to the glass polymer eyeball, and then reach the ceramic eyeball of living beings to present, artificial eyes, like only seen from appearance, nearly have no difference with the human eye, can rotate more freely equally. And " electronic eyes " It is on the basis of these, let the artificial eyeball look at things, at present, the most advanced " electronic eyes " Only the comparison that U.S.A. studies is ripe, but still need to allocate the high power camera, stimulate the nerve of brain through quite complicated electric pulse means, can only reach and see the level of the rough outline of object clearly at short range. The reporter knows, Professor Li YuBao's research has already had a gratifying good beginning, because of having foreshadowing of studying in earlier stage, what make of active material of living beings of nanometer can move the outer cover of eyeball at present, verified, can totally be with organizing inclusively, can grow together with muscles, blood vessel tightly by animal's experiment. Compared with such new material, it is too fragile to make the outer cover of movable eyeball of ceramic biomaterial, the metal material is too hard. Can affirm, the nanometer eyeball has already had the very good one that can move the function at present, is only used in improving looks, give and lack the person of the eyeball it with the perfect whole, this kind of eyeball has been already quite ripe. Then, can it be with depending on the thing is combined soon? Is there quite arduous work to do to reach this realm? As the reporter asks this question, Professor Li YuBao has not covered up at all. He tells reporters, the seminar is carrying on " electronic eyes " inside the outer cover of nanometer at present The circuit system designs, this is the most central part of nanometer eyeball. After waiting for the circuit to design finishing, will assemble with the eyeball outer cover of nanometer, will also need to carry on animal's experiment after succeeding. Because difficulty very large subject this, how long does it take bad to estimate examining. At present, seminar members are tackling key problems wholeheartedly. In the afternoon of December 19, when the reporter makes the telephone again, Professor Li YuBao's voice is much more calm. He tells reporter, some enterprise incoming telegrams express willingness to invest the development of the eyeball project of nanometer, in this way so, the speed that the nanometer eyeball studies can be accelerated. To the excessive propagation of some medias at present, Professor Li YuBao feels a bit uneasy, he hopes the various circles of society pay close attention to supporting the research and development of the nanometer eyeball, but don't entertain the impractical expectation to the nanometer eyeball.
