Silver nanoparticlesali ndi mawonekedwe apadera a kuwala, magetsi, ndi matenthedwe ndipo akuphatikizidwa muzinthu zomwe zimachokera ku photovoltaics kupita ku biological and chemical sensors.Zitsanzo zimaphatikizapo ma inki opangira, ma paste ndi ma fillers omwe amagwiritsa ntchito ma nanoparticles a siliva pamayendedwe awo apamwamba amagetsi, kukhazikika, komanso kutentha kocheperako.Mapulogalamu owonjezera amaphatikizanso kuwunika kwa ma cell ndi zida za Photonic, zomwe zimatengera mwayi pazithunzi zamtundu wa nanomatadium.Kugwiritsidwa ntchito kofala kwambiri ndikugwiritsa ntchito ma nanoparticles asiliva popaka ma antimicrobial, ndipo nsalu zambiri, makiyibodi, mabala, ndi zida zamankhwala tsopano zili ndi ma nanoparticles asiliva omwe mosalekeza amatulutsa ma ayoni asiliva otsika kuti ateteze ku mabakiteriya.

Silver NanoparticleOptical Properties

Pali chidwi chochuluka chogwiritsa ntchito mawonekedwe owoneka bwino a silver nanoparticles monga gawo lothandizira pazinthu zosiyanasiyana ndi masensa.Ma nanoparticles a siliva amatha kuyamwa ndi kumwaza kuwala ndipo, mosiyana ndi mitundu yambiri ya utoto ndi utoto, ali ndi mtundu wotengera kukula ndi mawonekedwe a chinthucho.Kugwirizana kwamphamvu kwa nanoparticles siliva ndi kuwala kumachitika chifukwa ma elekitironi conduction pa zitsulo pamwamba kukumana oscillation pamodzi pamene anasangalala ndi kuwala pa wavelengths enieni (Chithunzi 2, kumanzere).Imadziwika kuti surface plasmon resonance (SPR), kugwedezeka kumeneku kumabweretsa kufalikira kwamphamvu komanso kuyamwa kwamphamvu.M'malo mwake, ma nanoparticles asiliva amatha kutha bwino (kubalalitsa + kuyamwa) magawo a mtanda mpaka kuwirikiza kakhumi kuposa gawo lawo la mtanda.The amphamvu kubalalitsa mtanda gawo amalola wocheperapo 100 nm nanoparticles kuti mosavuta visualized ndi maikulosikopu ochiritsira.Pamene 60 nm siliva nanoparticles aunikiridwa ndi kuwala koyera amawoneka ngati owala abuluu poyambira magwero omwaza pansi pa maikulosikopu yamdima (Chithunzi 2, kumanja).Mtundu wonyezimira wa buluu ndi chifukwa cha SPR yomwe ili pachimake pa 450 nm wavelength.Katundu wapadera wa siliva wa nanoparticles wozungulira ndikuti mawonekedwe apamwamba a SPR amatha kusinthidwa kuchokera ku 400 nm (kuwala kwa violet) mpaka 530 nm (kuwala kobiriwira) posintha kukula kwa tinthu tating'onoting'ono ndi refractive index pafupi ndi tinthu tating'ono.Ngakhale kusintha kwakukulu kwa kutalika kwa mawonekedwe a SPR kupita kudera la infrared la electromagnetic spectrum kumatha kutheka popanga ma nanoparticles asiliva okhala ndi ndodo kapena mawonekedwe a mbale.

 

Silver Nanoparticle Applications

Silver nanoparticleszikugwiritsidwa ntchito muukadaulo wambiri ndikuphatikizidwa muzinthu zambiri zogulira zomwe zimatengera mwayi wawo wofunikira wa kuwala, conductive, ndi antibacterial properties.

  • Kugwiritsa Ntchito Diagnostic: Silver nanoparticles amagwiritsidwa ntchito mu biosensors ndi ma assay angapo pomwe zida zasiliva za nanoparticle zitha kugwiritsidwa ntchito ngati ma tag achilengedwe kuti azindikire kuchuluka kwake.
  • Kugwiritsa Ntchito Mankhwala Oletsa Bakiteriya: Silver nanoparticles amaphatikizidwa muzovala, nsapato, utoto, mabala, zida, zodzoladzola, ndi mapulasitiki chifukwa cha antibacterial properties.
  • Conductive Ntchito: Silver nanoparticles ntchito inki conductive ndi Integrated mu nsanganizo kumapangitsanso matenthedwe ndi magetsi madutsidwe.
  • Optical Applications: Silver nanoparticles amagwiritsidwa ntchito kuti akolole bwino kuwala komanso kuti azitha kuyang'ana mawonekedwe owoneka bwino kuphatikiza zitsulo zowonjezera fulorosenti (MEF) ndi kufalikira kwapamtunda kwa Raman (SERS).
