Project description

Investigation and detection of melanoma cancer cells in lymph fluid using microfluidics technology. In this research project both infrared (IR) analysis and photoacoustic (PA) measurement were selected for the detection and analysis of cells.

In the IR method, cells will be exposed by mid-IR electromagnetic wave in the region of 3-4 µm. Mammalian cells compose of phospholipid molecules and these molecules consist of alkane chain (polymers of CH2). The stretch vibrations of CH2 place in 3-4 µm and accordingly, mid-IR exposure interacts with cells in this region. This interaction can differentiate healthy and malignant cells due to the differences in their membrane properties.

Photoacoustics is a phenomenon based on optical absorption. In PA a pulsed source excites sample in an appropriate frequency. When a cell receives a pulse, it absorbs the light and then there will be a conversion of optical to thermal to mechanical energy in the form of expansion and contraction. So, regular cell movement because of consecutive pulse collision results in propagation of acoustic waves in surrounding media.
