Methods and systems for plasmonically enhanced bionanoantennas for tagging, tracking, and locating targets of interest at long distances in both day and nighttime conditions. The nanoantennas are used to tag a target of interest and emit a wavelength to impart a unique biometric signature. The nanoantennas are detectable by selectively harvesting and plasmonically enhancing incident light in the visible region, then upconverting that energy through an activated phosphor.
