Fiberless Optoelectrodes for Multicolor Neural Stimulation

6575 – Optogenetics is a relatively new technology in the field of neuroscience that combines genetic targeting of specific neurons or proteins with optical technology for imaging or control of the targets within a neural circuit. Neurons now may be controlled with optogenetics for fast, specific excitation or inhibition within systems as complex as freely moving mammals. Optogenetics is based on... Read More

Optoelectronic microprobe for tissue diagnostics

6217 – Overview: Accurate pancreatic tissue classification for the diagnosis and differentiation of pancreatic andenocarcinoma and chronic pancreatitis Background: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is commonly used to detect early-stage pancreatic adenocarcinomas, but is hindered by poor negative predictive value (cannot accurately exclude the presence of cancer)...

Reconfigurable Mesh Filters for Broadband Terahertz/Infrared Wave Modulation

5731 – A research team at the University of Michigan has developed a terahertz (THz) modulator that exhibits broadband, high amplitude modulation index. The use of THz technologies in many industries including semiconductor metrology, food quality processing, homeland security, medical imaging and communications, has led to staggering growth in the field in the last decade. Efficient light sources... Read More

A Compact Lens Array System

5745 – Researchers at the University of Michigan, as part of the Electrical Engineering and Computer Science Department have developed a low-cost, high-resolution and portable microscope system for biological imaging and analysis. Optical microscopy is the standard used for biological system visualization as well as identification, diagnosis and monitoring of many diseases including sickle-cell... Read More

Sensitive Intra-Cavity Biosensing Using Energy Transfer

4778 – Optofluidic lasers bring together nanophotonics and microfluidics and have been envisioned as sensitive biological and chemical sensors. Currently, they are limited by the laser wavelength, which must match that of the absorption wavelength of the dyes used. Energy transfer optofluidic lasers are far more efficient, but only a handful of them have been successfully demonstrated thus far.... Read More

Whole Spectrum Fluorescence Detection

3046 – Fluorescence measurements are an invaluable tool for a wide variety of applications in various fields, including chemistry, biomedical science, and clinical research. A primary advantage of measuring fluorescence over absorption is its high selectivity and sensitivity. One of the most important considerations for a fluorescence detection system is to separate fluorescence signals from... Read More
