TNNI3 and myocardial infarction: Currently, the diagnosis of myocardial infarction mainly relies on the detection of biomarkers, especially cTn isoforms I and T (cTnI and cTnT).[40a] Wang et al. synthesized a luminol‐AgNPs@ZIF‐67 nanocomposite which was microporous, although toxic, Co‐based zeolitic imidazolate frameworks ZIF‐67 decorated with luminal‐capped Ag nanoparticles (luminol‐AgNPs) on the surface.
