Cell-Penetrating Peptides: Applications in Tumor Diagnosis and Therapeutics
Since their identification over twenty-five years ago, the plethora of cell-penetrating peptides (CPP) and their applications has skyrocketed.These 5 to 30 amino acid in length peptides have the unique property of breaching the cell membrane barrier while carrying cargoes larger than themselves into cells in an intact, functional form.CPPs can be c
