Biosensor Technology Allows for Faster MS Detection

Biosensor technology will make it simple to diagnose and detect diseases such as cancer heart disease and multiple sclerosis with the development of a testing kit. Through such testing, such diseases may be diagnosed pretty much like today’s common home pregnancy test. Testing and diagnosis of such diseases can take more or less 15 minutes.

A team of researchers from the University of Leeds have developed a form of biosensor technology that makes use of antibodies to detect certain biomarkers in the body. Biomarkers are molecules found in the body that also acts as markers for certain diseases. The said technology offer a faster means for testing such diseases compared to the current testing methods used.

Current testing methods for detecting disease markers include ELISA or Enzyme Linked Immunosorbant Assay. The said testing method, first developed in the 1970’s uses blood and urine samples to test for biomarkers associated with certain diseases. The process takes almost 2 hours to complete and can be very costly. The new biosensor technology developed by the University of Leeds scientists can do the said test for 15 minutes and even less.

The biosensor technology was developed under the ELISHA project, a collaboration of European scientists and commercial partners. The technology makes use of new techniques of attaching antibodies to innovative surfaces and new electronic measurement methods that requires no reagents or labels.

The technology under the ELISHA project was made possible in coordination with Dr. Paul Millner from the Faculty of Biological Sciences at the University of Leeds. The study was managed by Dr. Tim Gibson. "We believe this to be the next generation diagnostic testing. We can now detect almost any analyte faster, cheaper and more easily than the current accepted testing methodology", says Dr. Millner.

The Leeds researchers believe that the new technology can be developed into a small handy device the size of a mobile phone where different sensor chips can be inserted. Adds Dr. Millner, "We’ve designed simple instrumentation to make the biosensors easy to use and understand. They’ll work in a format similar to the glucose biosensor testing kits that diabetics currently use."
