gold nanostar synthesis with a silver seed mediated growth method

Nano ölçekli kolloidler fiziksel, kimyasal ve optik özellikleri, malzeme bileşimi, boyut ve şekil 1-5 bağlıdır . Foto-termal ablasyon, uyuşturucu dağıtımı ve diğer pek çok biyomedikal uygulamaları 6 nano-kolloidler kullanarak büyük bir ilgi var. Altın özellikle düşük toksisite 7-9 kullanılır. Metal nano-kolloidler bir özellik, güçlü bir yüzeye plazmon rezonans 10 sahip olmasıdır . Yüzey plazmon rezonans modu zirve metal nano-kolloidler yapısı ve kompozisyon bağlıdır. Yüzey plazmon rezonans modu ışık ile uyarılır olduğundan biyolojik doku geçirgenlik 11, 12 maksimum olduğu yakın kızılötesi pik absorbans ihtiyaç vardır. Biz yıldız şeklinde nanopartiküller 13-15 veya Nanostars 16 olarak da bilinen yıldız şeklinde kolloidal altın, sentezlemek için bir yöntem sunar . Bu yöntemi olarak dayanmaktadıranizotropik büyüme için altın kolloidler 17-22 çekirdeklenme ajan olarak kullanılan gümüş tohumları içeren tanıyamıyor. Çıkan altın kolloid Taramalı elektron mikroskobu (SEM) analizleri nanoyapıların% 70 Nanostars olduğunu gösterdi. Parçacıkların% 30 diğer decahedra ve rhomboids amorf kümeleri vardı. Nanostars absorbans zirve, yakın kızıl ötesi (840 nm) olarak tespit edildi. Böylece, yöntem, özellikle foto-termal ablasyon, biyomedikal uygulamalar için uygun altın Nanostars üretir.
