Ifeza ya nanoparticlesbifite ibikoresho byihariye bya optique, amashanyarazi, nubushyuhe kandi byinjizwa mubicuruzwa biva kuri fotokoltaque kugeza kuri biologiya na chimique.Ingero zirimo wino ziyobora, paste hamwe nuzuza zikoresha ifeza ya nanoparticles kugirango ikoreshe amashanyarazi menshi, ituze, hamwe nubushyuhe buke.Porogaramu yinyongera zirimo kwisuzumisha hamwe nibikoresho bya fotonike, bifashisha imiterere ya optique yibintu bya nanomaterial.Ikintu gikunze kugaragara cyane ni ugukoresha nanoparticles ya silver kugirango yandike mikorobe, kandi imyenda myinshi, clavier, kwambara ibikomere, hamwe nibikoresho bya biomedical ubu birimo nanoparticles ya silver ikomeza kurekura urwego ruto rwa ion kugirango irinde bagiteri.

Ifeza NanoparticleIbyiza

Hariho inyungu ziyongera mugukoresha optique ya optique ya silver nanoparticles nkibigize imikorere mubicuruzwa na sensor zitandukanye.Ifeza ya nanoparticles ikora muburyo budasanzwe mu gukurura no gukwirakwiza urumuri kandi, bitandukanye n’irangi ryinshi n’ibara ryinshi, bifite ibara riterwa nubunini nuburyo imiterere yabyo.Imikoranire ikomeye ya nanoparticles ya feza nu mucyo ibaho kubera ko electroni ziyobora hejuru yicyuma zihungabana hamwe iyo zishimiwe numucyo muburebure bwihariye (Ishusho 2, ibumoso).Azwi nkubuso bwa plasmon resonance (SPR), iyi ihungabana itera imbaraga zidasanzwe zo gutatanya no kwinjiza ibintu.Mubyukuri, nanoparticles ya silver irashobora kugira kuzimangana neza (gutatanya + kwinjiza) ibice byambukiranya inshuro icumi kurenza igice cyambukiranya umubiri.Igice gikomeye cyo gutatanya igice cyemerera sub 100 nm nanoparticles kugaragara byoroshye na microscope isanzwe.Iyo 60 nm ifeza nanoparticles imurikirwa numucyo wera bigaragara nkubururu bwerurutse butanga isoko munsi ya microscope yumwijima (Ishusho 2, iburyo).Ibara ry'ubururu ryerurutse riterwa na SPR igeze ku ntera ya 450 nm.Umutungo udasanzwe wa nanoparticles ya feza ni uko ubu burebure bwa SPR bushobora guhuzwa kuva kuri 400 nm (itara rya violet) kugeza kuri 530 nm (itara ryatsi) uhindura ingano yingingo hamwe nigipimo cyaho cyangiritse hafi yubuso.Ndetse no guhinduranya kwinshi kwumurambararo wa SPR ugana mukarere ka infragre ya electromagnetic spécran irashobora kugerwaho mugukora nanoparticles ya feza ifite inkoni cyangwa isahani.

Ifeza Nanoparticle Porogaramu

Ifeza ya nanoparticleszirimo gukoreshwa muburyo bwinshi bwikoranabuhanga kandi ryinjijwe mubice byinshi byibicuruzwa byabaguzi bifashisha ibyiza bya optique, bayobora, na antibacterial.

• Gusuzuma Gusuzuma: Ifumbire ya nanoparticles ikoreshwa muri biosensor hamwe nubushakashatsi bwinshi aho ibikoresho bya silver nanoparticle bishobora gukoreshwa nkibimenyetso byibinyabuzima kugirango tumenye umubare.
• Porogaramu ya Antibacterial: Nanoparticles ya silver yinjizwa mumyenda, inkweto, amarangi, kwambara ibikomere, ibikoresho, kwisiga, na plastiki kubintu bya antibacterial.
• Gukoresha Amashanyarazi: Nanoparticles ya silver ikoreshwa muri wino yayobora kandi igahuzwa mubigize imbaraga kugirango izamure amashanyarazi n'amashanyarazi.
• Porogaramu ikoreshwa neza: Nanoparticles ya silver ikoreshwa mugusarura neza urumuri no muburyo bwiza bwa optique ya optique harimo na fluorescence yibyuma byongerewe imbaraga (MEF) hamwe na Raman ikwirakwiza hejuru (SERS).
