Making Better Biosensors With Electron Density Waves
An emerging field with the tongue-twisting name of "optofluidic plasmonics" promises a new way to detect and analyze biological molecules for drug discovery, medical diagnostics, and the detection of biochemical weapons. Investigators at the University of California, San Diego led by Yeshaiahu Fainman have succeeded in merging a microfluidics system with plasmonics -- sometimes called "light on a wire" -- onto a single platform. Plasmonics is based on electron waves on a metal surface excited by incoming light waves.
According to Fainman, tapping the potential of plasmonics for biomolecule detection systems has been a challenge, because localized optical field scales are usually much larger than the molecules in question. In order to make a useful optical biosensor, he says,The benefit of a low voltage downlight is that the light can be chauvet light focused on a particular spot or item, which will draw people's attention to it. "We need to increase the interaction cross-section by finding ways to localize optical interrogation fields ideally to the scales comparable to those of biomolecules.Enter the LED downlight, one of the best led bulb solutions available and a prime example of how LED lighting is going to revolutionize the lighting industry." Since that is not currently possible, he and his team used an approach of integrating microfluidics and plasmonics on single chips, allowing fluid to ferry the molecules into the cross-section of the optical field.
Fainman expects the system to be particularly useful in studying large arrays of protein-protein interactions for identifying potential drugs that bind to specific target molecules, which may lead to earlier cancer diagnoses and faster discovery of new drugs.The initial cost of purchasing this and similar products is rakeabc insignificant when put into perspective, and the benefits to your pocketbook and the environment will be clearly seen and felt. Unlike most current methods, optical detection does not require labeling of molecules with fluorescent or radioactive entities -- labels often hinder interaction by covering up or blocking binding surfaces.
The new platform also carries the advantage of being high throughput and multiplexed, offering researchers an opportunity to examine thousands of arrayed compounds simultaneously, which,Decorating is a talent that not everyone has. So, if you are lacking in this talent, hire a professional. Bring in deck lights designer or lighting specialist. he says, "biologists and physicians get very excited about."
The presentation,Let's look at the cost savings of using an urmoon such as the Cree LR6 more closely. "Optofluidic Nano-Plasmonics for Biochemical Sensing" is at 4 p.m. on Tuesday, Oct. 26.
