The upside of chemotherapy is that it attacks cancer cells and kills them. The downside – and a steep downside it is – is that it is composed of highly toxic compounds that attack other cells of the body, too, resulting in any number of harmful side effects, from anemia to hair loss to nausea and vomiting.
The question concerning researchers is how do we deliver chemotherapy drugs to the harmful cells and leave the healthy cells alone?

This article will interface you with the step by step things required when you are about to make your own Pulse oximeter.
Principles of Pulse Oximetry Technology:
The principle of pulse oximetry is based on the red and infrared light absorption characteristics of oxygenated and deoxygenated hemoglobin. Oxygenated hemoglobin absorbs more infrared light and allows more red light to pass through. Deoxygenated (or reduced) hemoglobin absorbs more red light and allows more infrared light to pass through. Red light is in the 600-750 nm wavelength light band. Infrared light is in the 850-1000 nm wavelength light band.
