ALB and cancer: It will be possible to extend this strategy to incorporate other inorganic PSs with NIR wavelength, such as osmium analogs.[28] The four biotin‐binding pockets are still accessible after modification to incorporate multiple copies of targeting ligands for enhanced internalization into TNBC in a more controlled fashion compared to other platforms such as human serum albumin.[20] The in situ assembly of the RuAvi platform with functional b‐FK peptides, which targets FPR‐1‐expressing cancer cells, allows rapid screening through this approach.
