The biologically synthesized GT\u2010AgNPs were characterized through a series of spectral analyses. The UV\u2013visible spectroscopy of the GT\u2010AgNPs exhibited a\n                    <jats:italic>\u03bb<\/jats:italic>\n                    max at 417\u2009nm. Fourier Transform\u2010Infrared spectroscopy indicated the presence of functional groups (hydroxyl, amines, alkynes, esters, ethers, and thiols) involved in the capping and stabilization of AgNPs. X\u2010ray Diffraction analysis validated the crystalline structure. Electron microscopic studies revealed that synthesized GT\u2010AgNPs are spherical\u2010shaped. Dynamic light scattering indicated an average particle size of 86.3\u2009nm. The zeta potential value &gt;\u2009\u221230\u2009mV suggested that GT\u2010AgNPs are more stable. The detection of Hg\n                    <jats:sup>2+<\/jats:sup>\n                    through colorimetric analysis demonstrated that the introduction of GT\u2010AgNPs into varying concentrations of Hg\n                    <jats:sup>2+<\/jats:sup>\n                    ions resulted in a significant color change from brownish yellow to a colorless solution, thereby recording the Limit of Detection to be 0.6\u2009\u03bcM and the Limit of Quantification as 1.82\u2009\u03bcM. Results of the recovery study using various micromolar (0.25\u20130.75\u2009\u03bcM) concentrations of Hg\n                    <jats:sup>2+<\/jats:sup>\n                    ions spiked with drinking and tap water showed a relative standard deviation of less than 5% and a recovery rate\u2009&gt;\u200991%. Considering the sensitivity and selectivity of GT\u2010AgNPs, this calorimetric assay clearly emphasized its potential in detecting Hg\n                    <jats:sup>2+<\/jats:sup>\n                    ions in contaminated aquatic ecosystems.
