Thin-film transistors (TFTs) are powerful devices in semiconductor manufacturing and form the basis of countless electronic devices, such as memory chips, photovoltaic cells, logic gates, and sensors. An interesting alternative to inorganic TFTs (silicon) is organic TFTs (OTFTs), which offer the possibility of mass production by using the conventional printing technology and working with low-cost materials. However, numerous inherent problems still remain, especially concerning the…

(Phys.org)—One of nanotechnology's greatest promises is interacting with the biological world the way our own cells do, but current biosensors must be tailor-made to detect the presence of one type of protein, the identity of which must be known in advance.

Engineers develop graphene-based biosensor that works in three ways at once

Two young researchers working at the MIPT Laboratory of Nanooptics and Plasmonics, Dmitry Fedyanin and Yury Stebunov, have developed an ultracompact, highly sensitive nanomechanical sensor for analyzing the chemical composition of substances and detecting biological objects, such as viral disease markers, which appear when the immune system responds to incurable or hard-to-cure diseases, including HIV, hepatitis, herpes, and many others. The sensor will enable doctors to identify tumor…

Abián Bentor Socorro-Leránoz, a telecommunications engineer of the NUP/UPNA-Public University of Navarre, has designed optical resonance-based biosensors for use in medical applications like the detection of coeliac disease. Besides achieving greater resolution and sensitivity, the materials used in these devices are much cheaper and more versatile than the ones used in current technologies (mainly gold and noble metals), so they could offer a potential alternative in the design of…

Researchers create first entropy-stabilized complex oxide alloys

It's only a centimeter long, it's placed under your skin, it's powered by a patch on the surface of your skin and it communicates with your mobile phone. The new biosensor chip developed at EPFL is capable of simultaneously monitoring the concentration of a number of molecules, such as glucose and cholesterol, and certain drugs.

Biosensors: A handy kit

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

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.

Scientists have been exploring new ways to "smell" signs of cancer by analyzing what's in patients' breath. In ACS' journal Nano Letters, one team now reports new progress toward this goal. The researchers have developed a small array of flexible sensors, which accurately detect compounds in breath samples that are specific to ovarian cancer.

We know that exhaled breath contains biomarkers that point to presence of existing disease, including cancer, but their detection is challenging without bu
