Abstract
A method for detecting local shear stress values using molecular rotors that allows for an extremely sensitive determination of a shear stress field or a flow field, even at very low flow rates. In one embodiment, molecular rotors may be adhered to a fiber optic probe or other solid surface, and the fluorescence emission of those molecular rotors may be probed at a location of the fiber optic probe tip or other solid surface. In another preferred embodiment, rotors may be adhered to another solid surface, such as any glass or polymer substrate that may be pre-functionalized (e.g., quartz, polystyrene or silicate glass) to create a probe that may then be used for in vivo as well as in vitro viscosity measurements. In another embodiment, molecular rotors may be dissolved in a target solution, and emission intensity obtained by one of several techniques.
