Production of the nanoparticles using leaf of Muntingia calabura L. as bioreductor and potential as a blood sugar nanosensor

Research on the synthesis of gold nanoparticles using Muntingia calabura L. leaf extract as a bioreductor and its potential analysis as a blood sugar nanosensor has been done. The synthesis Au nanoparticles are characterized and applied as sensors to detect glucose. The results show that gold nanoparticles have been successfully synthesized with a maximum wavelength of 544 nm. The measurements with PSA show that the average size of the gold nanoparticles is 78.2 nm. The gold nanoparticle-based glucose sensor design has a measurement range of 1-4 mM with a regression is 0.9248, minimum detection limit of the sensor at a concentration of 0.1500 mM and a maximum detection limit is 4.1744 mM with sensitivity is 0.6837 A. mM⁻¹.mm⁻².
