“…Many functional peptide libraries have actually been described in the literature, with different sequences and functions, offering a versatile platform of delivery agents to localize PS conjugates in different kinds of cells and tissues. 48 Covalently linked PS-peptide biohybrids can be synthesized, taking advantage of mild synthetic organic methodologies such as amide [49][50][51][52][53]77,78,81,[85][86][87]89,[91][92][93]95,97,104,105 or sulphonamide 54 bond formation, palladium-catalysed cross-coupling reactions, 55,56 click-chemistry reactions [57][58][59]81,94 and isothiocyanate chemistry, 60,82 among other strategies. Supramolecular approaches have also been used toward self-assembled peptide nanofibers, 61 nanodots, 62 vesicles, 63 light harvesting complexes, 64 arrays 65 or polymeric micelles with a peptide-decorated surface, 66 among others.…”
