detection of toad's physiology signals under thermoplasmonic effect ‎

Cardiovascular diseases (cvds) are leading cause of mortality worldwide, accounting for ‎‎17.3 million deaths per year, a number that is expected to grow to more than 23.6 million by ‎‎2030.therefore the need for developing health-monitoring systems (for hospitals, clinical, ‎or home settings) that can provide efficient services to patients with cardiovascular ‎diseases is becoming increasingly important, particularly in medium and large urban ‎agglomerations. thus, the present study aims to propose two dimensional flexible and ‎wearable gold covered plasmonic samples as a physiological signal recorder, in which ‎chips with nano array of resonant nanowire patterns performing in an integrated platform ‎of plasmonic devices. the produced surface plasmon waves in our main chip were paired ‎with an electric wave from the heart pulse and it use for recording and detecting the ‎heartbeat of a toad with high accuracy. this measurement was performed in normal state ‎and under external laser heating process when we used aunss nanoparticles to check the ‎ability of signal recording and also thermoplasmonic effect onto the toad’s heart signal. ‎our results show that our sensor was enough sensitive for detection while raising the body ‎temperature of the toad and changing its heart rate as flatting t and p waves by ‎thermoplasmonic effect.‎
