Valè enpòtan aplikasyon an ajan Nanoparticle

Sifas plasmon lan se yon jan de ptik pwopriyete nano-matyè lè yo interaction ak limyè. Nanoparticle an ajan sifas eleman bon tèt chaje expositions valè enpòtan aplikasyon nan jaden analiz chimik yo rayi, D' biologiques, ajan Nanoparticle amélioration sifas spectroscopie elatriye. Couplage nanoparticules ki se yon fason efikas pou kontwole pwopwiyete sifas la ak lòt eleman Yonizasyon. Ajan Nanoparticle sepandan, ki jan pou yo fòm yon roman nano-estrikti fonksyonèl une a distans associé efektif echèl (<5nm) of="" noble="" metal="" nanoparticles="" remains="" a="" scientific="">

Zhang, yon chèchè Xiamen Enstiti ki sou latè Rare materyèl Enstiti syans ak teknoloji a Chinwa Academy nan syans yo, travay sere-sere ak pwofesè-nan Inivèsite Xiamen. Ak sipò nasyonal fondasyon syans natirèl ak plan pèp Young la, ajan Nanoparticle papye a te devlope yon metòd assemblage diferan gwosè an lò nanoparticules (<250 nm)="" with="" different="" side="" long="" silver="" cubes=""><160nm), silver="" nanoparticle="" and="" the="" distance="" of="" the="" particle="" gap="" (1-5nm)="" can="" be="" controlled="" by="" the="" ultrathin="" silica="" shell,="" the="" assembly="" yield="" of="" au-ag="" two="" polymer="" was="" nearly="" 30%.="" the="" team's="" assembly="" mechanism,="" silver="" nanoparticle="" the="" influence="" factors="" such="" as="" assembly="" yield="" were="" deeply="" analyzed="" and="" discussed,="" the="" scattering="" spectra="" of="" single="" gold-silver="" two="" polymer="" were="" studied="" by="" means="" of="" single="" particle="" scattering="" spectroscopy,="" and="" the="" coupling="" fano="" resonant="" peaks="" were="" found="" by="" the="" silver="" of="" the="" assembled="" structure="" synergetic="" surface.="" the="" surface="" enhanced="" raman="" spectroscopy="" shows="" that="" the="" assembled="" structure="" has="" high="" performance="" of="" electric="" field="" enhancement.="" silver="" nanoparticle="" the="" structure="" is="" promising="" to="" be="" applied="" in="" the="" field="" of="" surface="" plasmon="" sensing,="" surface="" and="" other="" ionization="" catalysis.="" relevant="" results="" have="" been="" published="" in="" nanoscale="" (2016,="" 8="" (5):="">

Ajan métalliques lajman ki itilize nan nou chak jou lavi tou tankou plizyè medikal traitements, ajan Nanoparticle kòm yon rezilta nanotechnologie avans, Nanoparticle an ajan an ajan nanoparticules (apwe sa yo rele AGNPS) fè pwofi pi gwo benefis. Men, a grandi nan aplikasyon pou AGNPS nan jaden plizyè Inevitabman kondwi a anpil gwo risk nanoparticules, ni tèt chaje pou anviwònman sekirite ak sante moun. Nan dènye ane sa yo, chèchè gen évalué toksisite de AGNPS, te ap chache pou chèche fòmil cellulaire moléculaire toksisite yo.

Nano materyèl yo antre ak cellules, organelles ak aux (tankou pwoteyin, acides nucléique, Lipid, ik ak viv) Byolojik sistèm pou etabli yon seri de entèfas nanoparticules-biomolecules. An ajan Nanoparticle la entèraksyon fizik-chimik aktif, cinétique, ajan Nanoparticle ak chalè transfere nan zòn interfacial sa a afekte pratik kèk, tankou fòmasyon pwoteyin yon kouwòn, sèlil kontak, len encapsulé matyè, sèlil absorption ak biocatalysis, tout moun ki fè konnen biocompatibility ak Byolojik risques de pas.
