Biosensor sniffs out explosives
Temple University School of Medicine researchers have developed a new biosensor that sniffs out explosives and could one day be used to detect landmines and deadly agents, such as sarin gas, according to a paper in the June issue of Nature Chemical Biology. view more (2007-05-09)
ANALYTICA 2004: Biochip Helps Avoid Allergic Reactions
Within the EU project "CD-CHEF" the Institut für Mikrotechnik Mainz GmbH (IMM) is involved in the development of a biosensor for the detection of gluten in food. As a disposable chip the biosensor permits the standardised extraction and analysis of food samples. At Analytica, the experts from Mainz present a first functional model which... view more...

New biosensor can detect bacteria instantaneously
A research group from the Rovira i Virgili University (URV) in Tarragona has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. view more (2009-09-09)
Photonic crystal biosensors detect protein-DNA interactions
Scientists at the University of Illinois have developed a new class of disposable, microplate-based optical biosensors capable of detecting protein-DNA interactions. Based on the properties of photonic crystals, the biosensors are suitable for the rapid identification of inhibitors of protein-nucleic acid and protein-protein interactions. view more (2008-09-24)
Biosensor for the prevention of diseases associated with air-conditioning systems
The aim of this project is the development of a biosensor for the rapid detection of the Aspergillus fungus. This new biosensor enables the prevention of allergies and associated infections involving air-conditioning systems, common in institutional and company buildings. view more (2004-03-05)
Hopkins researchers develop new tool to watch real-time chemical activity in cells
Attempts to identify potential drugs that interfere with the action of one particular enzyme linked to heart disease and similar health problems led scientists at Johns Hopkins to create a new tool and new experimental approach that allow them to see multiple, real-time chemical reactions in living cells. view more (2006-07-24)
New biosensor could save lives by giving faster medical analysis.
Every day accident and emergency units have to treat patients who have taken some sort of drug overdose. To give treatment doctors need to know what the patient has taken. The circumstances can make often this difficult to ascertain quickly. Researchers are developing a new kind of biosensor, which can determine in minutes if a patient's blood... view more...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply
Scientists at the Universitat Autonoma de Barcelona (UAB), in cooperation with the CSIC, have developed a new electro-chemical biosensor which detects the presence, in food, of very small amounts of atrazine -one of the most widely used herbicides in agriculture and which also has very long lasting effects on the environment- as well as... view more...

Immune Cell Communication, Cooperation Keys to Hunting Viruses, Jefferson Immunologists Show
Immunologists at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have used nanotechnology to create a novel 'biosensor' to solve in part a perplexing problem in immunology: how immune system cells called killer T-cells hunt down invading viruses. view more (2006-10-27)
Speedy diagnosis at the doctor's office
Biochemical reactions can be monitored with the help of biosensors, allowing rapid analysis of blood counts or identification of toxins in water or foodstuffs. The biosensors employ selective biochemical reactions, based on the so-called lock-and-key principle to detect specific. In the case of an immune response, for example, an antibody attaches... view more... (1999-07-01)
Study demonstrates rapid diagnosis of urinary tract infections with biosensor technology
For the millions of people who suffer from urinary tract infections each year and the doctors who treat them, a promising new biosensor technology has been developed that may replace antiquated testing methods and save precious health care dollars. view more (2006-02-03)
New ultrasensitive electronic sensor array speeds up DNA detection
A novel electronic sensor array for more rapid, accurate and cost-efficient testing of DNA for disease diagnosis and biological research has been developed by scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN). view more (2009-08-27)
Engineering chimeric polypeptides to illuminate cellular redox states
UIUC interdisciplinary team reports the design of chimeric polypeptides leading to development of noninvasive biosensors for potential application in biomedical research. view more (2008-01-24)
When proteins, antibodies and other biological molecules kiss, a new kind of biosensor can tell
When biological molecules kiss, a new kind of biosensor can tell. A new and deceptively simple technique has been developed by chemists at Vanderbilt University that can measure the interactions between free-floating, unlabeled biological molecules including proteins, sugars, antibodies, DNA and RNA. view more (2007-09-21)
Magnet Lab researchers make observing cell functions easier
Now that the genome (DNA) of humans and many other organisms have been sequenced, biologists are turning their attention to discovering how the many thousands of structural and control genes -- the "worker bees" of living cells that can turn genes on and off -- function. view more (2008-05-09)
Handheld DNA detector
A researcher at the National University at San Diego has taken a mathematical approach to a biological problem - how to design a portable DNA detector. view more (2008-03-11)
Light shines way to diagnosis - The Physics Congress 2003
A research team from the Institute of Photonics at the University of Strathclyde has developed an array of miniature ultra-bright light emitting diodes (LEDs), which they believe could form the basis of a biosensor detection system, allowing doctors to perform thousands of clinical tests all in one go. Team leader Professor Martin Dawson will be... view more... (2003-03-17)
