Label-free Cancer Cells Detection using Optical Sensors

There are various biophysical alterations on cancer cells, on one layer there are distorded electric field, in another layer, in the visual range electromagnetic fields, there are specific biophotonic emissions [1] and also, as is pointed out in this paper an specific light absorption wavelength range different from non cancerous cells, maybe is related to biophotonic signaling possibility or impossibility.
