Design and making a model/prototype of portable fiber-optic biosensors as alternate bio-analytical tools
It is found that there have been an increasing number of fluid-transmittable diseases in recent times. Among the many water related diseases, Cholera, typhoid fever and hepatitis A are three infamous and common examples. Besides water, viruses are also transmitted through blood and body fluids. An e...
