Nanoscale biological particles

The goal of this research thrust is to two fold: (1) develop an analytical and experimental framework to investigate the structural and dynamic properties of biological nanoscale surface particles, and (2) develop adaptive surfaces with reconfigurable topologies. We answer the following questions:

Engineering-enabled biology

What are the adhesive properties of individual nanoscale particles?
What are the vibrational and shock responses of individual particles? How do shape modifications influence the response?
What are the mechanical and dynamical properties of ensembles of nanoscale biological particles?

Bio-inspired design

How can we take inspiration from granule-like nanoparticles to create surfaces with adaptive topology?
How do nanoscale biological particles influence the aerodynamics, tribological, and hydrophobic properties of insects wings and how can we translate these principles to micro-robotic systems?

To answer these questions, we employ and develop multiple methods and techniques, including:

Experimental

scanning electron microscopy
materials characterization and testing
micro-mechanical testing
vibration characterization
manufacturing using additive manufacturing

Modeling

finite element analysis
dynamics and multi-physics modeling

This project is a collaboration with Dr. Marianne Alleyne’s group at the University of Illinois at Urbana Champaign and the Center for Integrated Nanotechnologies (CINT) at Sandia National Laboratories.
