De novo strategy of organic semiconducting polymer brushes for NIR-II light-triggered carbon monoxide release to boost deep-tissue cancer phototheranostics.

The integration of photoacoustic imaging (PAI) and photothermal therapy (PTT) within the second near-infrared (NIR-II) window, offering a combination of high-resolution imaging and precise non-invasive thermal ablation, presents an attractive opportunity for cancer treatment. Despite the significant promise, the development of this noninvasive phototheranostic nanomedicines encounters challenges that stem from tumor thermotolerance and limited therapeutic efficacy. In this contribution, we designed an amphiphilic semiconducting polymer brush (SPB) featuring a thermosensitive carbon monoxide (CO) donor (TDF-CO) for NIR-II PAI-assisted gas-augmented deep-tissue tumor PTT.

Electrochemiluminescence Biosensor for Ascorbic Acid Based on Target Transformation of Cell-Free RNA Transcription System and Duplex-Specific Nuclease-Assisted Recycling Amplification.

A cell-free RNA transcription system had been coupled with electrochemiluminescence (ECL) detection technology for the first time to develop an ascorbic acid (AA, acting as a model target) biosensor. The biosensor is composed of single-stranded DNA (ssDNA) sequences modified with alkynyl and azido groups, respectively, alongside an incomplete gene circuit framework. The addition of target AA and copper ions will cause the linkage of the two ssDNA sequences through a click chemistry reaction.
