Surface-enhanced Raman scattering (SERS) from organic molecules is used to study how geometry affects plasmonic enhancement in noble metal nanoparticles using super-resolution analysis techniques coupled with scanning ...

Development of high average power lasers has historically been limited by the properties of available gain media. As a result it is either too costly or impractical to employ lasers in many applications for which they would ...

Many promising nanotechnologies, such as bit-patterned magnetic media, require highly ordered, defect-free monolayers of particles. Thus, there is a need for cost-efficient and robust manufacturing techniques to reliably ...

The magnetic and physical properties of oxide-free, ligand passivated, iron nanoparticles were studied using superconducting quantum interference device (SQUID) magnetometry and synchrotron based X-ray radiation. Particles ...

For 40% of currently discovered drugs which are poorly water soluble, engineering amorphous nanoparticles with rapid dissolution and enhanced solubility can improve their absorption. Antisolvent precipitation by mixing ...

Supercritical carbon-dioxide has long been considered an inexpensive, safe and environmentally benign alternative to organic solvents for use in industrial processing. However, at readily accessible conditions of temperature ...

Cancer is among the leading causes of death in the United States and the world. Using combined ultrasound (US) and photoacoustic (PA) imaging can provide both anatomical and molecular information of cancerous cells for ...

Molecular photoacoustic imaging is an exciting new field that promises to visualize molecular indicators of disease. The objective of this dissertation is to progress molecular imaging by providing a photoacoustic microscopy ...
