Synthesis and Optically-induced Assembly of Colloidal Nanomaterials
Brief Description of Project:
The Ndukaife Research group conducts research at the interface between nanophotonics and microfluidics to develop new lab-on-a-chip devices for trapping, manipulation, sorting and sensing of nanometric objects. This project involves synthesizing and exploring the optical and thermal properties of colloidal nanomaterials including amorphous silicon and silver nanocubes, and their use for designing metasurfaces for lab-on-a-chip device applications. Silicon colloids and silver nanocubes are known to exhibit strong light scattering and produce distinct colors depending on their size, owing to their strong Mie-type and plasmonic resonance respectively. In addition, they also strongly absorb light and hence can serve as nanoscale sources of heat providing the means to engineer heat distribution.
This project will involve the synthesis of these nanomaterials and their assembly using new techniques being developed in the PI's lab.
This project is best suited for a student interested in chemistry or optics. Students should have completed at least general chemistry with a corresponding lab course.
Nature of Supervision:
The student will work closely with Prof. Ndukaife and graduate students.
