#Team develops ultra sensitive biosensor from molybdenite semiconductor Move over graphene. An atomically thin two-dimensional ultrasensitive semiconductor material for biosensing developed by researchers at UC Santa barbara promises to push the boundaries of biosensing technology in many fields from health care to environmental protection to forensic industries.

Based on molybdenum disulfide or molybdenite (Mos2) the biosensor materialsed commonly as a dry lubricanturpasses graphene's already high sensitivity offers better scalability

and low-cost biosensors that can eventually allow single-molecule detectionhe holy grail of diagnostics and bioengineering research said Samir Mitragotri co-author and professor of chemical engineering and director of the Center for Bioengineering at UCSB.

While graphene has attracted wide interest as a biosensor due to its two-dimensional nature that allows excellent electrostatic control of the transistor channel by the gate

and high surface-to-volume ratio the sensitivity of a graphene field-effect transistor (FET) biosensor is restricted fundamentally by the zero band gap of graphene that results in increased leakage current leading to reduced sensitivity explained Banerjee

Monolayer or few-layer Mos2 have a key advantage over graphene for designing an FET biosensor:

and increases the abruptness of the turn-on behavior of the FETS thereby increasing the sensitivity of the biosensor said Banerjee.

Moreover the channel length of Mos2 FET biosensor can be scaled down to the dimensions similar to those of small biomolecules such as DNA

The Mos2 biosensors demonstrated by the UCSB team have provided already ultrasensitive and specific protein sensing with a sensitivity of 196 even at 100 femtomolar (a billionth of a millionth of a mole) concentrations.

Biosensors based on conventional FETS have been gaining momentum as a viable technology for the medical forensic

Such biosensors allow for scalability and label-free detection of biomoleculesemoving the step and expense of labeling target molecules with florescent dye.

and low-cost ultrasensitive biosensors continued Kis who is connected not to the project. Explore further: New rapid synthesis developed for bilayer graphene and high-performance transistors More information:

These findings could one day lead to super-dense low-power circuits as well as ultra-sensitive biosensors and gas sensors, the investigators added.

and ultra-sensitive and low-power biosensors and gas sensors to enhance the Internet of things. However, Banerjee cautions that TFETS are designed not for speed

#Polymer Nanobrushes Grab Selected Bacteria for Pathogen Detection A Texas A&m Agrilife Research engineer and a Florida colleague have developed a biosensor that can detect listeria bacterial contamination within two

The biosensor she is working on is still in the prototype stage of development, but in a few years she envisions a hand-held device that will require hardly any training to use.

"The selection process the polymers use to select for specific bacteria in the listeria biosensor is very similar to the squid's cilia.

"Currently, the listeria biosensor is about the size of a postage stamp, with two wires leading to two etched conductive areas.

Also in the works is a disposable paper-based biosensor that can be disposed of after one use.
