Iinanoparticles zesiliverezineepropati ezizodwa, zombane, kunye ne-thermal kwaye zifakwe kwiimveliso ezivela kwi-photovoltaics ukuya kwi-biological and chemical sensors.Imizekelo ibandakanya ii-inki eziqhubayo, iipaste kunye nezizalisi ezisebenzisa i-nanoparticles yesilivere ngokuqhuba kombane, ukuzinza, kunye namaqondo obushushu aphantsi e-sintering.Izicelo ezongezelelweyo ziquka i-molecular diagnostics kunye nezixhobo ze-photonic, ezithatha inzuzo yeempawu ze-novel optical zala ma-nanomaterials.Isicelo esixhaphakileyo kukusetyenziswa kwe-nanoparticles yesilivere kwii-antimicrobial coatings, kunye nempahla emininzi, iibhodibhodi, ukunxitywa kwamanxeba, kunye nezixhobo ze-biomedical ngoku ziqulethe i-nanoparticles yesilivere eqhubekayo ukukhulula inqanaba eliphantsi le-ion zesilivere ukubonelela ngokhuseleko kwiibhaktheriya.

Isilivere yeNanoparticleIiPropathi zokubona

Kukho umdla okhulayo ekusebenziseni iimpawu ze-optical ze-nanoparticles zesilivere njengecandelo elisebenzayo kwiimveliso ezahlukeneyo kunye neenzwa.Iinanoparticles zesilivere zisebenza ngokugqwesileyo ekufunxeni nasekusasazeni ukukhanya kwaye, ngokungafaniyo nedayi ezininzi kunye ne-pigment, zinombala oxhomekeke kubukhulu kunye nokumila kwesuntswana.Ukusebenzisana okunamandla kwee-nanoparticles zesilivere kunye nokukhanya kwenzeka ngenxa yokuba ii-electron zokuqhuba kwi-metal surface zingena kwi-oscillation ehlangeneyo xa ichulumanciswa kukukhanya kumaza athile (Umfanekiso 2, ekhohlo).Eyaziwa ngokuba yi-surface plasmon resonance (SPR), olu tshintsho lukhokelela ekuhlakazekeni okunamandla ngokungaqhelekanga kunye neempawu zokufunxa.Enyanisweni, i-nanoparticles yesilivere inokuba nokuphela okusebenzayo (ukusasazeka + ukufunxa) amacandelo anqamlezayo ukuya kumaxesha alishumi amakhulu kunecandelo lawo elinqamlezayo lomzimba.Icandelo elinqamlezayo lokusasazeka livumela ukuba i-sub 100 nm nanoparticles ibonakale ngokulula nge-microscope eqhelekileyo.Xa i-nanoparticles yesilivere engama-60 nm ikhanya ngokukhanya okumhlophe ibonakala njengeebhulowu eziqaqambileyo zomthombo wokuchithachitha phantsi kwe-microscope yasendle emnyama (Umfanekiso 2, ekunene).Umbala oluhlaza okwesibhakabhaka oqaqambileyo ngenxa ye-SPR ephakanyiswe kwi-450 nm wavelength.Ipropati ekhethekileyo ye-nanoparticles yesilivere ye-spherical kukuba le SPR i-peak wavelength inokulungiswa ukusuka kwi-400 nm (ukukhanya kwe-violet) ukuya kwi-530 nm (ukukhanya okuluhlaza) ngokuguqula ubungakanani be-particle kunye ne-index refractive yendawo kufuphi ne-particle surface.Nokutshintsha okukhudlwana kwe-SPR peak wavelength ukuya kwindawo ye-infrared ye-electromagnetic spectrum inokufezekiswa ngokuvelisa iinanoparticles zesilivere ezinentonga okanye iimilo zepleyiti.

ISilver Nanoparticle Applications

Iinanoparticles zesiliverezisetyenziswa kubuchwephesha obuninzi kwaye zibandakanywe kuluhlu olubanzi lweemveliso zabathengi ezithatha ithuba lezinto zabo ezinqwenelekayo ezibonakalayo, eziqhubayo, kunye nezokulwa ne-antibacterial.

• Izicelo zokuxilonga: I-nanoparticles yesilivere isetyenziselwa kwii-biosensors kunye novavanyo oluninzi apho izinto zesilivere ze-nanoparticle zingasetyenziselwa njengeempawu zebhayoloji zokufumanisa ubuninzi.
• Ukusetyenziswa kweAntibacterial: I-nanoparticles yesilivere ifakwe kwiimpahla, izihlangu, iipeyinti, ukubopha amanxeba, izixhobo zombane, izimonyo, kunye neeplastiki kwiimpawu zabo zokulwa ne-antibacterial.
• Izicelo zokuqhuba: Ii-nanoparticles zesilivere zisetyenziselwa ii-inki eziqhubayo kwaye zihlanganiswe kwii-composites zokuphucula i-thermal kunye nombane.
• Ukusetyenziswa kwe-Optical Application: Iinanoparticles zesilivere zisetyenziselwa ukuvuna ukukhanya ngokufanelekileyo kunye ne-optical spectroscopies eyandisiweyo kuquka i-metal-enhanced fluorescence (MEF) kunye ne-surface-enhanced Raman scattering (SERS).
