Ama-nanoparticles esilivazinezinto ezihlukile zokubuka, zikagesi, nezishisayo futhi zifakwa emikhiqizweni esukela ku-photovoltaics kuya kuzinzwa zebhayoloji nezamakhemikhali.Izibonelo zifaka o-ink abaqhubayo, ama-paste nama-filler asebenzisa ama-nanoparticles esiliva ekusebenzeni kwawo okuphezulu kukagesi, ukuzinza, namazinga okushisa aphansi e-sintering.Izinhlelo zokusebenza ezengeziwe zifaka ukuxilonga kwamangqamuzana kanye nemishini yezithombe, ezisebenzisa ngokunenzuzo izici zokubona ezintsha zalawa ma-nanomaterials.Uhlelo lokusebenza oluvame ukwanda ukusetshenziswa kwama-nanoparticles esiliva ezinto zokulwa namagciwane, futhi izindwangu eziningi, amakhibhodi, ukubopha amanxeba, namadivayisi we-biomedical manje aqukethe ama-nanoparticles ayisiliva akhulula ngokuqhubekayo izinga eliphansi lama-ion esiliva ukuze anikeze isivikelo kubhaktheriya.

I-Silver NanoparticleI-Optical Properties

Kunesithakazelo esikhulayo sokusebenzisa izici zokubona ze-nanoparticles esiliva njengengxenye esebenzayo emikhiqizweni ehlukahlukene nezinzwa.Ama-nanoparticles esiliva asebenza kahle ngokumangalisayo ekumunceni nasekuhlakazeni ukukhanya futhi, ngokungafani nodayi abaningi nemibala, anombala oncike kusayizi nokuma kwezinhlayiyana.Ukusebenzisana okunamandla kwama-nanoparticles esiliva nokukhanya kwenzeka ngenxa yokuthi ama-electron e-conduction endaweni yensimbi ahlangana ngokuzungeza lapho ejatshuliswa ukukhanya kumaza athile (Umfanekiso 2, kwesokunxele).Okwaziwa ngokuthi i-surface plasmon resonance (SPR), lokhu kuzulazula kubangela izici eziqine ngokungavamile zokuhlakazeka nokumunca.Eqinisweni, ama-nanoparticles esiliva angaba nokushabalala okuphumelelayo (ukuhlakazeka + ukumuncwa) izingxenye eziphambanayo eziphindwe kashumi ezinkulu kunesigaba sazo esiphambanayo somzimba.Ingxenye enqamulayo ehlakazekayo eqinile ivumela ama-sub 100 nm nanoparticles ukuthi abonakale kalula ngesibonakhulu esivamile.Lapho ama-nanoparticles esiliva angu-60 nm akhanyiswa ngokukhanya okumhlophe avela njengama-scatterers omthombo wamaphuzu aluhlaza okwesibhakabhaka ngaphansi kwesibonakhulu sensimu emnyama (Umfanekiso 2, kwesokudla).Umbala oluhlaza okwesibhakabhaka ogqamile ungenxa ye-SPR efinyelela phezulu ku-450 nm wavelength.Isici esiyingqayizivele sama-nanoparticles esiliva ayindilinga ukuthi le wavelength ephakeme ye-SPR ingashunwa ukusuka ku-400 nm (ukukhanya oku-violet) kuya ku-530 nm (ukukhanya okuluhlaza) ngokushintsha usayizi wezinhlayiyana kanye nenkomba yendawo ekhanyayo eduze kwendawo yezinhlayiyana.Ngisho namashifu amakhulu we-SPR peak wavelength aphumele endaweni ye-infrared ye-electromagnetic spectrum angafinyelelwa ngokukhiqiza ama-nanoparticles esiliva anenduku noma umumo wepuleti.

ISilver Nanoparticle Izicelo

Ama-nanoparticles esilivazisetshenziswa kubuchwepheshe obuningi futhi zifakwe ohlwini olubanzi lwemikhiqizo yabathengi esizakala ngezinto zazo ezifiselekayo ze-optical, conductive, kanye ne-antibacterial.

• Izicelo Zokuxilonga: Ama-nanoparticles esiliva asetshenziswa kuma-biosensors nasezivivinyweni eziningi lapho izinto ezisiliva ze-nanoparticle zingasetshenziswa njengamathegi ebhayoloji ukuze kutholwe inani.
• Izicelo Zokulwa Namagciwane: Ama-nanoparticles esiliva ahlanganiswa engutsheni, ezicathulweni, opende, amanxeba amanxeba, izinto zikagesi, izimonyo, namapulasitiki ngenxa yezakhiwo zawo zokulwa namagciwane.
• Izicelo Eziqhubayo: Ama-nanoparticles esiliva asetshenziswa kuma-inks okuqhuba futhi ahlanganiswe nezinhlanganisela ukuze kuthuthukiswe ukuqhutshwa kokushisa nogesi.
• I-Optical Applications: Ama-nanoparticles esiliva asetshenziselwa ukuvuna ukukhanya kanye nokwenza ngcono ama-optical spectroscopies afaka i-metal-enhanced fluorescence (MEF) kanye ne-surface-enhanced Raman scattering (SERS).
