We report the development of a new strategy for the chemical analysis of live cells based on protein spherical nucleicacids (ProSNAs). The ProSNA architecture enables analyte detection via the highly programmable nucleicacid shell or a functional protein core. As a proof-of-concept, we use an i-motif as the nucleicacid recognition element to probe pH in living cells. By interfacing the i-motif with
Herein are provided, inter alia, compositions including boronic esters, which in the presence of H
