Calcium Sensor for Photoacoustic Imaging

open access: yesJournal of the American Chemical Society, 2017
We introduce a selective and cell-permeable calcium sensor for photoacoustics (CaSPA), a versatile imaging technique that allows for fast volumetric mapping of photoabsorbing molecules with deep tissue penetration. To optimize for Ca2+-dependent photoacoustic signal changes, we synthesized a selective metallochromic sensor with high extinction ...
