The helmet is fitted with unique biosensors that measure physiological life signs. Monitoring the pilot heartbeat, blood flow and oxygen level in the blood stream.

"Indeed, the videogame identifies boredom, excitement or anxiety in patients-and their cognitive responses-with the help of emotion recognition technologies and biosensors.

##Leveraging expertise in optical biosensors and hemorrhagic fever diseases our collaborative research effort has produced a highly sensitive device with the potential to perform rapid diagnostics in clinical settings.##

In the controllable biosensor developed by doctoral candidate Nicolas Lapique the gene responsible for the output signal is not active in its basic state as it is installed in the wrong orientation in the circuit DNA.

In the controllable biosensor developed by doctoral candidate Nicolas Lapique the gene responsible for the output signal is not active in its basic state as it is installed in the wrong orientation in the circuit DNA.

The new method produces the combination of desired properties in as small a package as possible Bawendi says which could help pave the way for particles with other useful properties such as the ability to bind with a specific type of bioreceptor or another

as well as serve as plant-based biosensors and stress reducers. By adapting the sensors to different targets,

"We have developed a smart SERS biosensor for the rapid screening of bladder cancer, "says Olivo."

A new study shows that this feature could facilitate easier nanoscale manufacturing of biosensors and plasmonic devices with intricate high-density surface structures.

And of course any biosensor needs to be accurate. You need to know the numbers. Is it 100%accurate?

#New absorber will lead to better biosensors Biological sensors or biosensors are like technological canaries in the coalmine.

By converting a biological response into an optical or electrical signal they can alert us to dangers in our external and internal environments.

An optical biosensor works by absorbing a specific bandwidth of light and shifting the spectrum

The narrower the band of absorbed light is the more sensitive the biosensor. Currently plasmonic absorbers used in biosensors have a resonant bandwidth of 50 nanometers said Koray Aydin assistant professor of electrical engineering and computer science at Northwestern University's Mccormick School of engineering and Applied science.

It is significantly challenging to design absorbers with narrower bandwidths. Aydin and his team have created a new nanostructure that absorbs a very narrow spectrum of light#having a bandwidth of just 12 nanometers.

This ultranarrow band absorber can be used for a variety of applications including better biosensors. We believe that our unique narrowband absorber design will enhance the sensitivity of biosensors Aydin said.

It's been a challenge to sense very small particles or very low concentrations of a substance.

Their optical biosensor for single unlabelled molecules could also be a breakthrough in the development of biochips:

and Biosensors at the Max Planck Institute for the Science of Light has succeeded now in amplifying the interaction of light with DNA molecules to the extent that their photonic biosensor can be used to observe single unlabelled molecules and their interactions.

"The researchers have tested their optical biosensor with a sample containing both an exactly matching DNA fragment

#Graphene sensor tracks down cancer biomarkers An ultrasensitive biosensor made from the wonder material graphene has been used to detect molecules that indicate an increased risk of developing cancer.

The biosensor has been shown to be more than five times more sensitive than bioassay tests currently in use and was able to provide results in a matter of minutes opening up the possibility of a rapid point-of-care diagnostic tool for patients.

The biosensor has been presented today 19 september in IOP Publishing's journal 2d Materials. To develop a viable bionsensor the researchers from the University of Swansea had to create patterned graphene devices using a large substrate area

and low pressure to form the basis of the biosensor. The researchers then patterned graphene devices using semiconductor processing techniques before attaching a number of bioreceptor molecules to the graphene devices.

These receptors were able to bind to or target a specific molecule present in blood saliva or urine.

In their study the researchers used x-ray photoelectron spectroscopy and Raman spectroscopy to confirm that the bioreceptor molecules had attached to the graphene biosensor once fabricated

and then exposed the biosensor to a range of concentrations of 8-OHDG. When 8-OHDG attached to the bioreceptor molecules on the sensor there was a notable difference in the graphene channel resistance

which the researchers were able to record. Results showed that the graphene sensor was capable of detecting 8-OHDG concentrations as low as 0. 1 ng ml-1

The graphene biosensor was also considerably faster at detecting the target molecules completing the analysis in a matter of minutes.

Moving forward the researchers highlight the potential of the biosensor to diagnose and monitor a whole range of diseases as it is quite simple to substitute the specific receptor molecules on the graphene surface.

which make it an ideal material for fabricating biosensors. Now that we've created the first proof-of-concept biosensor using epitaxial graphene we will look to investigate a range of different biomarkers associated with different diseases and conditions as well as detecting a number of different biomarkers on the same chip.

#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

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.

#Designing ultra-sensitive biosensors for early personalised diagnostics A new type of high-sensitivity and low-cost sensors,

called plasmonic biosensors, could ultimately become a key asset in personalised medicine by helping to diagnose diseases at an early stage.

In biosensors, protein molecules are identified by irradiating them with infrared light and by analysing the spectrum of the light they emit, known as a Raman spectrum.

To do so, the researchers attached bioreceptors, fragments of DNA engineered to recognise specific proteins, to the nanoantennas.

When the nanoantennas studded with the bioreceptors are incubated in a solution that contains the biomarkers to be detected,

they show the Raman fingerprints of both the bioreceptor and the biomarker, as Gucciardi points out.

who has been developing plasmonic biosensors at the University of Victoria, British columbia, Canada. He also believes that such approach will make medical care more cost effective."

The"end-users"of these biosensors have to understand that the development of these devices by researchers in many disciplines is a long process, notes Estévez.

She adds that these biosensors will need to be integrated with optical components, with electronics for reading out the measurements, software to process all data,

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