Karbon nanodot (KNDlar) olarak da bilinen karbon
nanoparçacıklar (KNDlar), karbon temelli nanoyapıların yeni ve özel bir üyesi
olarak bilinmektedir. KNDların elektronik, optik, katalitik, biyouyumlu
ve,kimyasal olarak inert olmaları ve yüksek fotolüminesans (PL) davranışı gibi
özellikleri ile boyalar, ağır metal temelli kuantum noktaları (QDs) yerine
alternatif olarak kullanılmaya başlanmış ve biyomedikal araştırmalar ve enerji
alanlarındaki popülariteleri de hızla artmıştır. Bu çalışmada, floresans
özellikli karbon nanoparçacıkların (FKNDlar) keçiboynuzu pekmezinin doğal
karbon kaynağı olarak kullanılması ile sentezlenmesi konu alınmıştır. Bu amaç
doğrultusunda, kolay ve ekonomik açıdan avantajlı olduğu bilinen yeşil sentez
yöntemlerinden biri olan, ısıl sentez yöntemi kullanılmış ve sentezlenen karbon
nanoparçacıkların yüzeyleri; farklı moleküler ağırlıklarda polietilen glikol
(PEG Mn:300~20000)ile pasivize edilmiştir. Sentezlenen
FKNPların, alan emisyonlu taramalı elektron mikroskobu (FE-SEM), XRD, UV
spektrofotometresi, floresans emisyon spektroskopisi ve dinamik ışık kırılım
yöntemleri ile karakterizasyonları yapılmıştır. Karakterizasyonlar sonucunda
pasivasyon ajanının değişen molekül ağırlığına göre parçacıkların yüzey
özelliklerinin ve buna bağlı olarakta floresans spektrum cevaplarının değiştiği
ve kor parçacık boyutu yaklaşık olarak 10-15 nm olarak belirlenenen
nanoparçacıkların hidrodinamik çaplarının pasivasyon ajanının Mn’sine
göre değişiklik gösterdiği belirlenmiştir. Floresans özellikteki karbon
nanoparçacıklar biyogörüntüleme ve teşhis amaçlı nanoetiket ve ilaç taşıyıcı
sistem olarak biyomedikal uygulamaları ile fotovoltaik cihazların ve yeni nesil
katalizörlerin geliştirilmesinde kullanılma potansiyeline sahiptirler.
