Laser Spray Ionization (LSI) Method for Mass Spectrometry Imaging
Technology Summary: Laser Spray Ionization (LSI) is a novel inlet ionization method for mass spectrometry invented at WSU which can be used to create predominately multiply charged ions from solid samples at atmospheric pressure. Unlike MALDI ionization methods which are typically limited to producing singly charged species for larger molecules, LS...

Marangoni Optofluidic Tweezers (MOT)
There is currently a great deal of interest in using small droplets as containers for chemical reactions. Optical methods for droplet manipulation are attractive because they offer control without an on chip structure; however forces from optical tweezers tend to be in the pN range. Wayne State University researchers have developed a new m...

High Gain Infrared Collector and Data Node
An infrared collector employs a concentrator formed of a plurality of spatially related gradient-indexed (GRIN) lenses and a photo detector interconnected by optical fibers. Since the GRIN lenses are arranged on a hemispherical shell the concentrator is relatively insensitive to the direction of the incoming infrared radiation. Optical fibers ...

Sub-monolayer detection with surface selective vibrational spectroscopy
This invention describes a new system and method for performing surface-selective spectroscopic detection with high sensitivity and low detection limits particularly in the visible and fingerprint mid-infrared spectral regions. The method offers a substantial improvement, 10-fold or more, over existing techniques. This invention has already been r...

Imaging Tandem Mass Spectrometry: Reduction to Practice
Currently, tandem mass spectrometry is typically performed by selecting a single mass peak in a time of flight or quadrupole mass spectrometer, which is then fragmented through collision, after which the products are mass-selected in a quadrupole or similar secondary mass spectrometer. A Wayne State University researcher has developed an alter...
