Goridhe ndechimwe chezvinhu zvakagadzikana zvemakemikari, uye nanoscale goridhe zvimedu zvine zvakakosha zvemuviri nemakemikari zvimiro.Kare muna 1857, Faraday yakaderedza mhinduro yeAuCl4-mvura nephosphorus kuti iwane yakadzika tsvuku colloidal solution yegoridhe nanoppowders, iyo yakaputsa kunzwisisa kwevanhu nezveruvara rwegoridhe.Nano goridhe zvimedu zvakawanikwawo zvine fluorescence, supramolecular uye molecular recognition properties.Izvo chaizvo nekuda kweakakosha zvivakwa zvenano goridhe hupfu kuti vane yakafara kwazvo tarisiro yekushandisa muminda ye biosensors, photochemical uye electrochemical catalysis, uye optoelectronic zvishandiso.Mumakore achangopfuura, zvichibva pachimiro chekutsvuka-kushanduka kwepamusoro plasmon resonance peak yeAu nanoparticles mushure mekudsorption, iyo DNA uye carbohydrate mamorekuru akaremerwa nenano Au particles akaongororwa uye akawanikwa achibatsira muminda yekudzivirira, calibration. uye tracer.

Ndarama nanoparticlessemhando ye nanoparticles, inokwezva zvakanyanya nekuda kwekugadzikana kwavo, homogeneity uye biocompatibility.Iyo yepamusoro plasmon resonance zvivakwa uye kuunganidzwa kwegoridhe nano zvimedu, pamwe nekutsamira kwavo kune yekunze nharaunda, zvinoita kuti zvishandiswe zvakanyanya mukuzivikanwa kwemavara.Masimba akashumwa ekuunganidzwa kweAu nano zvimedu anosanganisira hydrogen bonding, ionic ligand saiti kupindirana, kurongeka kwesimbi, uye kusanganisa-muenzi.Ichishandisa sodium citrate seyakagadzikana, sodium citrate-yakagadziridzwa goridhe nanoparticles yakabudirira kugadzirwa uye yakashandiswa se colorimetric probes.Iyo yepamusoro penano goridhe probe yakachajiswa zvisina kunaka uye inogona kusanganiswa nyore nyore nemamorekuru anochajiswa anochajiswa kuburikidza nekuita kwe electrostatic.Mune BR buffer solution papH 4.6, propranolol inochajiswa zvakanaka nekuda kweprotonation, saka inogona kusanganiswa negoridhe nanoparticles, zvichikonzera shanduko yemuvara weiyo system, kuitira kumisikidza yakapusa colorimetric identification nzira yepropranolol.Panguva imwecheteyo, nekubatanidzwa kwegoridhe nano powders, iyo RRS kusimba kweiyo system inowedzera, saka iyo RRS nzira ine yakapusa fluorescence spectrophotometer sezvo detector inotangwa zvakare kuti ione propranolol.Kubva pane sodium citrate-yakagadziridzwa goridhe nan oparticles, colorimetric uye RRS nzira dzekutemesa propranolol dzakavambwa.

Hongwu Nano ine kwenguva refu uye yakagadzikana yekupihwa yemhando yepamusoro yegoridhe (Au) nano masisitimu, kuvimbiswa kwemhando, fekitori yakananga kutengesa, uye yemakwikwi mitengo.Ndapota usazeza kutibata kuti uwane rumwe ruzivo.
