Fabrication of micro fluidic channels for functionalizing lead selenide quantum dots for photovoltaic application

Microfluidic devices can be used for variety of applications. Fluid mixing, chemical reactions in small volumes are some of them. Micro fluidic channels are mainly used in biochemical analysis. There are many benefits in using these channels, such as decreased manufacture cost, reduced time of analysis. In this work soft lithographic technique is used for the fabrication of the micro fluidic channels. Using this micro fluidic channels we coated (capping) L-cysteine over Lead selenide quantum dots (PbSe QD's). Conducted assay and nitro prusside test to analyze the structure of the L-Cystein capped QDs. These L-Cystein capped QDs can found application in photovoltaics.
