Our current research activities focus on the three major areas A, B and C:

A) Sensors and Actuators Based on Self-Assembled Nanomaterials

In this area we explore novel types of chemiresistors and strain gauges based on self-assembled films of gold nanoparticles (AuNP). Currently we are starting activities to evaluate the potential of freestanding nanoparticle-based membranes as actuators and components in microelectromechanical systems (MEMS).
The figure below illustrates some of these activities. For more information click here.
