Highly sensitive sensors of molecular compounds based on globular photonic crystals

It is shown that a highly sensitive sensor of molecular structures can be implemented based on the use of globular photonic crystals with a molecular compound introduced into their pores. The technique under development allows performing the spectral analysis of individual molecules in photonic crystal pores. In particular, these experiments showed the possibility of detecting extremely small amounts of molecules of the type of Rhodamine-6G dissolved in an aqueous medium at concentrations ??10^?7 g/cm³ (??10^?10 mol/ml).
