Complementary atomic flame/molecular colorimetry dual-mode assay for sensitive and wide-range detection of cancer cells

Abstract

Since multicolor switch was involved in both Sr²⁺-related flame and precipitation reactions, these reactions can be thus utilized for constructing a complementary atomic flame/molecular colorimetry dual-mode sensing platform for a sensitive and wide-range analysis of cancer cells by virtue of the gas generation from platinum nanozyme-mediated hydrogen peroxide decomposition.
