In vitro sensor characterization. (a) Fluorescence emission spectrum at 785 nm excitation of SM8-3-wrapped HiPCO SWNT encapsulated in PEGDA-8000 hydrogel. (b) Fluorescence emission spectrum at 785 nm excitation of ss(AAAT)7-wrapped (6,5) CoMoCAT SWNT encapsulated in PEGDA-8000 hydrogel. (c)SM8-3-wrapped HiPCO SWNT hydrogel fluorescence increases with an addition of 100 μm progesterone in 1X PBS solution (n = 3). (d) (AAAT)7-wrapped (6,5) CoMoCAT SWNT fluorescence decreases with an addition of 100 μm riboflavin in 1X PBS solution. (e) Schematics of synthesis of the PEGDA hydrogels: monomer mixed with SWNT solution and initiator, degassed, pipped between two glass slides to control for thickness, and exposed to UV light to initiate free radical polymerization
