Development of an Analyzer for Size and Charge Characterization of Nanoparticles in Research and Training

Undergraduate researchers: Jeremy Stark

Professor researchers: Dr. M. K. Mazumder, Dr. J. Zhang, Dr. R. Sharma

Abstract:

This project will develop an analyzer for size and charge measurement of nanoparticles. The existing E-SPART analyzer measures the size and charge of particles between 1 and 30 ĂŽÂĽm. The proposed instrument will significantly advance the capabilities of the current E-SPART for its application to nanoscale materials with a goal to cover a range of 10 to 1000 nm in diameter.

Current Undergraduate Involvement:

The undergraduate researcher is mainly working on the development of the laser optical and signal detecting system of the instrument.

Grant awards: NSF grant No. 0526977, 2005 – 2008 (extended), $251,028
