Uniformly Oriented Diatom Frustule Monolayers: Formation and Analysis

PROJECT DESCRIPTION
Diatoms are unicellular, photosynthetic algae which are ubiquitous in aquatic environments. Their unique 3-D structured silica exoskeletons, also known as frustules, has drawn attention from a variety of research fields due to their extraordinary mechanical properties, enormous surface area, and unique optical properties.

The ability to uniformly control the frustule’s alignment/orientation is the key to realize their full potential in various technologies, such as ultrasensitive bio/chemical sensors and solar cells. In previous studies, multiple methods have been investigated for arranging diatoms in uniformly oriented compact monolayers. In this project, we will continue exploring innovative and simple ways to align these micro particles to form uniformly oriented compact monolayers, towards sensor fabrication and energy harvesting applications.

LEARNING GOALS
To fully understand the experimental process, the participants are expected to learn basic wet bench chemistry processing techniques, certain cleanroom fabrication techniques, as well as various micro- and nano-scale characterization techniques, and simulation techniques.
