Biomedical applications of MOEMS are limited only by the mankind imagination. Precision measurements on minute amounts of biological material could be performed by optical means with a remarkable accuracy. Although available in medical laboratories for general purposes, such analyzers are making their way directly to the users in the form of dedicated equipment. Such an example is a test kit to detect the existence of cardiac enzymes in the blood stream. Apart from the direct users, the medical personnel will make use of such tools given the practicality of the kit. In a large proportion of patients admitted to the hospital suspected of Acute Myocardial Infarction (AMI), the symptoms and electrocardiographic changes are inconclusive. This necessitates the use of biochemical markers of myocardial damage for correct exclusion or conformation of AMI. In this study the concept of MOEMS is applied for the detection of enzyme reaction, in which glass spectrums are scanned optically when enzyme molecules adsorb on their surface. This paper presents the optical behavior of glass spectrums under Horseradish Peroxide (HRP) enzyme reaction. The reported experimental results provide valuable information that will be useful in the development of biosensors for enzymatic detection. This paper also reports the dynamic behavior of different glass spectrums.
