Enhanced Colorimetric Detection of Volatile Organic Compounds Using a Dye‐Incorporated Photonic Crystal‐Based Sensor Array (Adv. Mater. 46/2024)

Volatile Organic Compounds In article number 2409297, Shu Yang and co-workers present an innovative approach to enhance volatile organic compound (VOC) sensing by integrating dyes with colloidal photonic crystals. The broadened reflection peak allows for augmented dye absorption originating from the overlap between the photonic bandgap edge and the dye absorption peak, leading to a more noticeable color change discernible to the naked eye, eliminating the need for signal amplification.
