Claim:
1. A method for producing a temperature-sensitive nanoporous fluorescent silica particle, the method comprising the steps of: creating a synthesizing solution comprising a silica precursor, at least two different fluorescent dyes, a catalyst, and a structure-directing agent; complexing the at least two different fluorescent dyes with said silica precursor to form said temperature-sensitive nanoporous fluorescent silica particles; and removing any uncomplexed silica precursor and fluorescent dye from said solution; wherein said at least two different fluorescent dyes inside said temperature-sensitive nanoporous fluorescent silica particles are coupled in Forster resonance energy transfer (FRET); wherein a ratio of fluorescent peaks in a fluorescent spectrum of said temperature-sensitive silica particle is dependent upon ambient temperature; and wherein said temperature-sensitive silica particles are between 8 nm to 100 μm.
