Building a Better Nanoparticle (alias Manipulating Nanoparticles with Electric and Magnetic Fields)

Abstract

 

The widespread use of nanoparticles in technology is still limited by the available tools at nanoscale to control their properties. Our group at Kansas State University and the at the Terahertz Reaction Control Group at ELI-ALPS, Hungary aims at developing technology useful to address these fundamental technical issues by studying nanoparticles in strong electric and magnetic fields. First, we have been studying the effect of inhomogeneous magnetic pulses on strong inhomogeneous magnetic fields, which can produce sufficient power of ultrasound to alter permeability of lipid bilayers. So called magnetoliposomes (liposomes loaded with magnetic nanoparticles) can be used to develop rapid drug release methodology to address the shortcomings of currently available liposomes delivery systems. Second, semiconducting nanoparticles exhibiting the property of quantum confinement (Quantum dots) have been shown to strongly interact with low frequency(terahertz) pulses allowing manipulation of charge carriers. Our goal is to manipulate charges in and around Quantum dots with the help of terahertz sources available at the Extreme Light Infrastructure attosecond light source facility in Hungary! Ultimately, we hope to produce ultrafast electronic light switch and to study nonlinear processes due to the presence of strong electric fields!
