The sensors make use of microfluidic technologyâ##developed by Abraham Stroock associate professor of chemical and biomolecular engineeringâ##that places a tiny cavity inside the chip.

Then simple polymerase chain reaction (PCR) technology can identify the code and reveal the origin of the product in about an hour right down to

and the current in the channel is modulated by the binding between embedded receptor molecules and the charged target biomolecules to

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

which can lead to high sensitivity even for detection of single quanta of these biomolecular species she added.

#Milestone single-biomolecule imaging technique may advance drug design Abstract: The first nanometer resolved image of individual tobacco mosaic virions shows the potential of low energy electron holography for imaging biomolecules at a single particle level--a milestone in structural biology and a potential new tool

for drug design. Knowing the detailed shape of biomolecules such as proteins is essential for biological studies and drug discovery.

Modern structural biology relies on techniques such as nuclear magnetic resonance (NMR), X-ray crystallography and cryo-electron microscopy to discover the tiny structural details of biomolecules.

All these methods, however, require averaging over a large number of molecules and thus structural details of an individual biomolecule are lost often.

Now researchers from the University of Zurich Switzerland have made a breakthrough by obtaining the first nanometer (one billionth of a meter) resolved image of individual tobacco mosaic virions,

Second, low energy electrons are harmless to biomolecules, "Longchamp said. In many conventional techniques such as transmission electron microscopy, the possible resolution is limited by high-energy electrons'radiation damage to biological samples.

Individual biomolecules are destroyed long before an image of high enough quality can be acquired. In other words, the low permissible electron dose in conventional microscopies is not sufficient to obtain high-resolution images from a single biomolecule.

However in low energy electron holography, the employed electron doses can be much higher--even after exposing fragile molecules like DNA or proteins to a electron dose more than five orders of magnitude higher

Sufficient electron dose in low energy electron holography makes imaging individual biomolecules at a nanometer resolution possible.

Kit could one day Be led by widely available Professor Jeffrey Bode of the Institute of Transformative Biomolecules at Nagoya University in Japan,

The chirality of these biomolecules also strongly affects the way in which they interact with other molecules,

Maureen Hansen a professor of molecular biology and genetics at Cornell says the advances won't be seen in commercially grown food crops for at least five or 10 years.

Some of the examples comprise materials that deliver biomolecules, rotate light, or control the flow of energy.

Currently, polymerase chain reaction (PCR) assays represent one technology widely used for pathogen detection but typically only a handful of microorganisms can be identified in a single test.

it becomes feasible to look at microarrays as everyday tools for use in the diagnostic laboratory. he beauty of the LLMDA is that it lets you identify unknown diseases that the researcher isn looking for,
