| Active NSOM Probes |
Active NSOM Probes for Imaging and Ion Sensing Probes Cantilevered and straight nanopipette probes can be filled with fluorescent materials. These active light sources can be provided with a variety of sensing capabilities. Sensors are currently available for H+, Na+, K+, Ca2+ and Cl-, other sensors are also available upon request.

Experimental arrangement of external illumination NSOM mode for ion sensing. A cantilevered nanopipette tip is used as a nanovessel for an ion-sensing dye, which is excited in epi-illumination. The AFM function is used to provide unprecedented control of a dye in an optical microscope.
