Abstract:  Non-blinking giant quantum dots (QDs) with robust silica coating are ideal light emitters in real-time 3D single particle tracking. Here we aim to couple the stable luminescence of giant QDs (d=16.2nm) to plasmonics to generate hybrid gQD@SiO2@Au probes (around 100nm) with highly localized electric field. This should enable us to visualize both physical structures and molecular features of endosomes by combining target locking 3D real time tracking method with Stimulated Raman Microscopy. The early stage progress includes synthesizing desired structures which are in good agreement with our simulation and optical characterization.
