Low-Cost Compact Optical Spectroscopy and Novel Spectroscopic Algorithms
Thu, Dec 8, 2022 2:00 PM - 3:00 PM EST
Dr. Caigang Zhu of the University of Kentucky, shares on a recently developed novel spectroscopic model with proper wavelength pairs that has been implemented with both a standard optical spectroscopy platform and a low-cost compact spectroscopy device. This model is utilized for the near real-time quantification of nanoparticle concentrations in biological tissue models. Both tissue-mimicking phantoms and ex vivo tissue sample studies show that these optical spectroscopic techniques can quantify concentrations in near real time with high accuracies of <5% error using a pair of narrow wavelengths. These techniques could potentially facilitate real-time monitoring of nanoparticle delivery in biological models using low-cost point-of-care optical spectroscopy platforms, which would significantly advance nanomedicine in cancer research.
Fused Silica in Radiation Environments
Tue, Dec 13, 2022 1:00 PM - 2:00 PM EST
An increasingly wide range of applications need to be able to function in harsh environments, not only on space missions but also here on Earth, in particle detectors, for example. It is important to understand radiation's key processes and their effects on fused silica in order to design optical instrumentation that can avoid harm to its systems, enabling it to complete its mission. Eduard Klett of Heraeus Conamic provides an overview of fused silica as an optical material and how it is affected by different types and doses of radiation. He classifies types of radiation and discusses their causes. Presented by Heraeus Conamic.
