Heart attacks are deadly and are getting common these days. Among these, silent heart attack is the most dangerous thing. A class 10 student from Tamil Nadu Student has developed a new technique that can non-invasively detect the risk of a silent heart attack. This advancement may save many lives. The technique involves frequently analyzing the presence of FABP3, a blood biomarker of heart attack without puncturing the skin. FABP3 is one of the smallest proteins that can be present in blood, and is charged negatively so it attracts to positive charges. When a small potential of positive charge is applied FABP3 accumulates on dermal capillaries, which can then be detected by ultra-violet (UV) quantification. In this process, UV light is passed through the thin skin in which FABP3 is accumulated and a sensor detects the amount of protein there, based on the how much of the light was absorbed.
