At an interface between two transparent media of different refractive index (glass and water), light coming from the side of higher refractive index is partly reflected and partly refracted. Above a certain critical angle of incidence, no light is refracted across the interface, and total internal reflection is observed. While incident light is totally reflected the electromagnetic field component penetrates a short (tens of nanometers) distance into a medium of a lower refractive index creating an exponentially detenuating evanescent wave.

What is diabetes

Diabetes is classed as a metabolism disorder.
There are three main types of diabetes:
Diabetes Type 1 - You produce no insulin at all.Diabetes Type 2 - You don't produce enough insulin, or your insulin is not working properly.Gestational Diabetes - You develop diabetes just during your pregnancy.

INTRODUCTION

CONTINUOUS blood glucose monitoring can help to significantly reduce (between 40% to 75%) the symptoms associated with diabetes . Currently, a few continuous blood glucose monitoring systems are commercially available which can continuously monitor the blood glucose level up to only a few days .A very promising approach to long-term continuous glucose monitoring is to implant a glucose sensor along with an electronic instrument, required for data measurement and communication, in the human body and measure the glucose level cont ....etc

ABSTRACT

Materials Science research is now entered a new phase where the structure and properties of materials are investigated, characterized and controlled at the nanoscale. Though as sophisticated as their larger counterparts, these devices are still burdened because they rely on an outside power. The size of the entire device is determined by the size of the power source. Batteries and other traditional sources are too large, and tend to negate the size advantages of nano devices. Also, batteries being used at present ....etc

Surface plasmon resonance
ABSTRACT

Surface plasmon resonance (SPR) is a phenomenon occurring at metal surfaces(typically gold and silver) when an incident light beam strikes the surface at a particular angle.Depending on the thickness of a molecular layer at the metal surface,the SPR phenomenon results in a graded reduction in intensity of the reflected light.Biomedical applications take advantage of the exquisite sensitivity of ....etc

History of surface plasmon resonance
• Since its first observation by Wood in 1902 ,the physical phenomenon of surface plasmon resonance (SPR) has found its way into practical applications in sensitive detectors, capable of detecting sub-monomolecular coverage.
• Wood observed a pattern of ‘‘anomalous’’ dark and light bands in the reflected light, when he shone polarized light on a mirror with a diffraction grating on its surface.
• a complete explanat ....etc
