Two novel methods of fluorescent imaging including molecular rotors and cotton bolls are presented here. Molecular rotors are a subgroup of fluorescent molecules with the ability to form twisted intramolecular charge transfer (TICT) complexes. They can be used for fluorescent imaging of flow patterns due to their unique property of viscosity sensitive quantum yield. Cotton bolls emit fluorescence when the chlorophyll on their exterior carpal wall isphotoexcited. A pest complex of stink bugs infests cotton boll crops and causes damage. A non-invasive method to determine damage to cotton bolls by stink bugs is developed for possible field applications of preventative measurements to minimize damage.
