Cervical Dilation Gauging Device for Training Obstetrics Students
Organization: University of North Dakota
The device, or "cervimeter," is shaped like a pair of tongs with two arms that fit on the index and middle fingers of an examiner on one end, and is attached to a gauge on the other end. As the examiner spreads his/her fingers to measure the cervical dilation of a patient during labor, the gauge accurately indicates the degree of dilation.

Liquid Chromatograph on a Chip
Organization: University of Cincinnati
The field of microelectromechanical structures (MEMS) involves the development of miniaturization technology to control and characterize processes with instrumentation which is orders of magnitude smaller than what is currently available. The traditional approach to on-line chemical detection has been to develop highly selective sensors. This approach has been plagued with a variety of difficulties, primarily developing suitably selective sensors for the enormous variety of problems faced. Chromatographic separation prior to detection reduces ...

Integrated PCR and Electrochemical Biosensor to Detect Biological Samples
Organization: University of California, Los Angeles (UCLA)
UCLA researchers have developed a novel microfluidic platform that integrates PCR amplification and sequence-specific real-time detection with electrochemical biosensors. Electronic sensor regions are incorporated into microfluidic channels that correspond to the annealing temperature zones. The sensor regions are fabricated with redox-labeled DNA probes attached on electrode surfaces. When these DNA probes come into contact and hybridize with PCR products, an electrochemical signal is produced and measured.
Detecting Compounds with Liquid Crystals
Organization: Wisconsin Alumni Research Foundation (WARF)
Although highly sensitive techniques already exist for monitoring gas phase chemicals in the environment, these methods involve expensive, complex instruments and processes such as mass spectroscopy, making them unsuitable for real-time use in the field. UW-Madison researchers have developed a novel method and device for detecting the presence of gas phase chemical compounds such as environmental contaminants with liquid crystals. The device consists of a thin film of liquid crystals overlaying a nanostructured surface that hosts receptors ...
System for Calculating the Spatial-Temporal Effects of Environmental Conditions on Animals
Organization: Wisconsin Alumni Research Foundation (WARF)
Current changes in global climate, land use and other human activities, such as the increased use of pesticides, can have a negative impact on the well being of animals. UW-Madison researchers have developed an accurate method to predict and thereby diminish or even prevent these negative effects. Their system uses an integrated set of models to incorporate all the conditions needed to accurately predict how animals (both ectotherms and endotherms) will react to changes in their surroundings. The software package contains three ...
Use of Liquid Crystals and Affinity Microcontact Printing to Detect Chemicals and Biomolecules
Organization: Wisconsin Alumni Research Foundation (WARF)
Many conventional methods, such as radioimmunoassay (RIA), enzyme-linked immunosorbent assay (ELISA) or surface plasmon reflectometry (SPR), can detect the presence of target molecules; however, these techniques are expensive and often require complex equipment and highly trained individuals, making them difficult to use routinely in the field. UW-Madison researchers have developed methods for using affinity microcontact printing and liquid crystals to simply and easily detect a ligand or receptor. Affinity microcontact printing captures a ...
Organization: Wisconsin Alumni Research Foundation (WARF)
Shock sensors are accelerometers that respond to specific levels of acceleration. The design usually consists of a proof mass and a flexible suspension. At a preselected level of acceleration, the deflection of the proof mass will typically contact an electric switch, just like a relay. A persistent challenge for shock sensors has been the closing and opening of electrical contacts. A very small proof mass may fail to break through surface films that may inadvertently form on the electrical contact. In addition, if the suspension ...
Spectroscopic Detection of Water Contaminants Using Glow Discharges from Liquid Microelectrodes
Organization: Wisconsin Alumni Research Foundation (WARF)
Threats to drinking water supplies from industrial and biochemical pollutants have created the need for rapid, on-site tools that detect and analyze trace contaminants in water. Current protocols for assessing water quality typically require transport of water samples to a laboratory for analysis with a plasma spectrometer. In plasma spectroscopy, a water sample is sprayed into a high-frequency, RF inductively-coupled plasma. Vaporized water droplets are then spectrally analyzed to determine the composition and quantity of impurities, such as ...

PNA Probes, Probe Sets, Methods and Kits for Detecting Listeria
Organization: Wisconsin Alumni Research Foundation (WARF)
Peptide nucleic acid (PNA) is a synthetic polyamide DNA mimic that can hybridize to DNA or RNA. Although it hybridizes readily with DNA and RNA, PNA is not equivalent to these nucleic acids in structure or function. Instead, it possesses a number of unique properties, including stability in biological samples, a long shelf life and the ability to hybridize with target nucleic acids independent of ionic strength. Additional properties of PNA include enhanced hybridization kinetics, improved mismatch discrimination and the ability to penetrate ...
A Portable Instrument for Surface Plasmon Resonance (SPR) Imaging

Surface plasmon resonance (SPR) imaging is a surface-sensitive, optical detection method for monitoring interactions between biomolecules (DNA, RNA and proteins) without the need for radioactive, fluorescent or other types of labeling (see WARF reference number P99196US for more information on SPR imaging). Current SPR imaging instruments are bench top-sized and thus can only be used in the laboratory. UW-Madison researchers have now constructed a smaller, portable SPR instrument for sample analysis in field situations. To reduce the size, ...
Device and Methods for Liquid Crystal-Based Bioagent Detection
Organization: Wisconsin Alumni Research Foundation (WARF)
Currently, most schemes for detecting bioagents or other biological molecules are based on relatively complex electronic, photonic and/or electrochemical methods, or on more elegant biomolecular methods, such as ELISA. However, the engineering-based approaches demand a high level of system integration and highly sensitive circuitry, leading to issues with cost, reliability and power consumption. The more biologically-oriented approaches are simple, but typically require a costly macro-scale spectrometry system to quantify the ...
