Joseph T. Hodges, A. Cygan, Piotr Maslowski, Katarzyna E. Bielska, S. Wojtewicz, J. Domyslawska, Hisashi Abe, R.S. Trawinski, R. Ciurylo
We describe a high sensitivity and high spectral resolution laser absorption spectrometer based upon the frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) technique. We used the Pound-Drever-Hall (PDH) method to lock the probe laser to the high

Recent Advances in Electrochemical Glyco-biosensing

Rebecca A. Zangmeister, Germarie Sanchez-Pomales
Biosensors based on electrochemical transduction mechanisms have recently made advances into the field of glycan analysis. These glyco-biosensor assays offer simple, rapid, sensitive and economical approaches to the measurement need for rapid glycan

Quantification and Compensation of Unintentional Analyte Aggregation in Electrospray Sampling

March 30, 2011

Mingdong M. Li, Suvajyoti S. Guha, Rebecca A. Zangmeister, Michael J. Tarlov, Michael R. Zachariah
Electrospray (ES) sources are commonly used to introduce non-volatile materials (e.g. nanoparticles, proteins, etc.) in to the gas phase for characterization by mass spectrometry and ion mobility. Recent studies in our group using electrospray ion mobility

Monitoring Photothermally Excited Nanoparticles via Multimodal Microscopy

May 19, 2010
Author(s)
Matthew L. Clarke, Shin G. Chou, Jeeseong Hwang
Generation of heat using optically excited nanoparticles can be beneficial or detrimental depending on the application. Therefore, clinically applicable studies are being pursued in an effort to achieve safe practices of nanoparticle-induced hyperthermia

Low-Cost, High-Throughput, Automated Counting of Bacterial Colonies

January 5, 2010
Author(s)
Matthew L. Clarke, Robert L. Burton, A. N. Hill, Maritoni A. Litorja, Moon H. Nahm, Jeeseong Hwang
Research involving bacterial pathogens often requires enumeration of bacteria colonies. Here we present a low-cost, high-throughput colony counting system consisting of colony counting software and a consumer-grade digital camera or document scanner. We
