Development of a Low- Cost, Portable Biosensor for Blood Protein Detection

This innovation offers a high level of medical diagnostic sensing abilities comparable to more costly clinical instrumentation. Current blood testing procedures are expensive and time consuming, and the equipment required is often bulky and difficult to transport. A new low-cost, portable technique has been developed to quickly and reliably detect specific proteins in a sample of human blood. The technique, described in the Sept. 1, 2011 issue of the Optical Society’s (OSA) open-access journal, Biomedical Optics Express, could help in a wide range of medical sensing applications, including diagnosing diseases like cancer and diabetes long before clinical symptoms arise.

Non-Invasive Instrument for Skin Cancer Screening

Andor Newton camera powers combined RS-OCT probe capable of both morphological and biochemical characterization of skin cancers. Skin cancer is the most common form of cancer in humans, with annual rates continuing to climb from their current estimate of just over three million new cases each year. Although all skin cancers share the likelihood of a favorable outcome if early diagnosis and complete resection are achieved, diagnosis is invasive, subjective, lengthy, and expensive, as it involves expert visual inspection, biopsy, and histopathology.

Experimental Modeling of Sterilization Effects for Atmospheric Entry Heating on Microorganisms

Silicon was chosen for sample coupons. The objective of this research was to design, build, and test an experimental apparatus for studying the parameters of atmospheric entry heating, and the inactivation of temperature-resistant bacterial spores. The apparatus is capable of controlled, rapid heating of sample coupons to temperatures of 200 to 350 ºC and above. The vacuum chamber permits operation under vacuum or special atmospheric gas mixtures.

Saliva Preservative for Diagnostic Purposes

This preservative can be used in remote areas without refrigeration for at least two months. Saliva is an important body fluid for diagnostic purposes. Glycoproteins, glucose, steroids, DNA, and other molecules of diagnostic value are found in saliva. It is easier to collect as compared to blood or urine. Un for tunately, saliva also contains large numbers of bacteria that can release enzymes, which can degrade proteins and nucleic acids. These degradative enzymes destroy or reduce saliva’s diagnostic value. This innovation describes the formulation of a chemical preservative that prevents microbial growth and inactivates the degradative enzymes. This extends the time that saliva can be stored or transported without losing its diagnostic value. Multiple samples of saliva can be collected if needed without causing discomfort to the subject and it does not require any special facilities to handle after it is collected.

Leak-Free Connection for Blood Pressure Monitoring Applications

Using proprietary molding techniques, the inner fitting features three sharp barbs designed specifically to securely hold the stiffer hoses common to blood pressure monitors. For precise blood pressure monitoring in hospitals and surgeries, the accurate handling of medical devices is paramount. Human error or device failure can result in inaccurate readings, which compromise the safety of patients, and it is critical, therefore, that device components, such as connectors, not only ensure a leak-free connection but are also simple and easy to use.

Mini-Sensor Measures Magnetic Activity in Human Brain

A recent study indicates that the technology may be used in magnetoencephalography (MEG), a noninvasive procedure that could advance the study of neurological diseases. A miniature atom-based magnetic sensor has passed an important research milestone by successfully measuring human brain activity. Experiments verified the sensor's potential for biomedical applications such as studying mental processes and advancing the understanding of neurological diseases.
