A method for detecting mercury (Hg) ions in an aqueous solution is described. The method includes contacting the aqueous solution with a chemosensor to form a mixture; and monitoring a change in a fluorescence emission profile of the chemosensor in the mixture to determine the presence or absence of Hgions in the aqueous solution. The chemosensor includes pyrene silica nanoparticles where at least one pyrene is bonded to a surface of a silica nanoparticle through an amide bond with a formula of, pyrene-C(&#x2550;O)NHR-silica nanoparticle, and where R is an alkyl chain.
