Co-polymer Stabilizers for Pressured Metered Dose Inhalers (pMDIs)

A series of novel co polymer surfactants with the general structure LAmEOnLAm were developed along with a Colloidal Probe Microscopy (CPM) method to optimize the surfactant composition using adhesion forces to improve stabilization of drug dispersions. This expands the range of biomolecules and micronized drug particles that can be formulated with pMDIs....

Broad Temperature Range MIS Hydrogen Sensors

WSU researchers have developed hydrogen sensors that differ from previous devices by employing aluminum nitride as an insulator in a metal insulator semiconductor structure. These new structures show a marked specificity for hydrogen under a wide range of conditions. Several prototype sensors with various applications have been tested results are available...

Novel Biosensor Based on Parylene Cantilevers

A Wayne State University researcher has developed a novel biosensor for DNA and protein microarray applications as well as lab-on-a-chip assays. The biosensor is composed of a micro-scale cantilever made of a polymer material with a modulus of elasticity significantly less than cantilever-based biosensors utilizing silicon nitride. Biosensors...

Programmable Antisiphon Shunt System (P-A-S-S)

Detailed Description Wayne State University researchers have developed a surgically implantable shunt system for controlling fluid flow from a relatively high-pressure region to a low-pressure region. This device can be used in the management of patients with hydrocephalus and is particularly useful to counteract postural intracranial hypotension...

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 are...

Stool/Tissue Preservation Device

WSU inventors have designed devices that enable small pieces of human tissue or stool to be rapidly immersed and preserved at room temperature in toxic preservatives without exposing the end user to the toxicants. Samples contained in the device can be safely stored or used for biochemical, molecular, and structural analysis. The device design...

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 reduced...
