Scientists develop platform to detect impact of alcohol publicity on crimson blood cells


New Delhi, March 6

Scientists have developed a platform to detect the effect of prolonged exposure to alcohol on red blood cells (RBC) through high-resolution measurements of their size, according to a statement on Saturday.

The high-resolution platform that shows the reduction in size of RBCs due to alcohol exposure can be tuned for a point-of-care screening of multiple conditions that alter the size and count of red cells in blood.

Although it is known that alcohol affects RBCs, the exact physiological changes are very subtle and difficult to measure.

In order to overcome this challenge, scientists led by Professor Gautam Soni from Raman Research Institute (RRI), an institution funded by the Department of Science & Technology (DST), have developed custom-made electro-fluidic platform that can detect the change by measuring the cell size in enhanced resolution.

The device made in RRI relies on the resistive pulse sensing principle. The team first developed techniques for making tiny micron (1/1000th of a millimetre) sized holes or micro-pores at the tip of a glass capillary with careful fabrication, flame polishing, and image verification.

Cells passing through the pore created very tiny electrical pulses, which give direct and most sensitive information of cell count and volume.

These results may also be used to explain the lack of oxygen-carrying capability of RBC under alcohol exposure leading to blurred vision, muscular in coordination, and altered mental states from alcohol abuse.

The research work, recently published in the ACS Sensors journal of the American Chemical Society, was carried out by researchers Saurabh Kaushik, Manohara M, KD Murugan under the guidance of Soni and V Sundaramurthy from National Centre for Biological Sciences (NCBS), Bangalore, the statement added.
