NPs of biopolymer‐based materials, such as proteins (collagen, silk, albumin, gelatin, β‐casein, and zein), protein‐mimicking polypeptides, and polysaccharides (alginate, chitosan, starch, pullulan, and heparin), as well as commonly used polymers, including poly (lactic‐co‐glycolic acid) (PLGA), poly(glycolic acid) (PGA), and poly(lactic acid) (PLA), are widely used as cancer therapy vehicles due to their lack of allergic reactions and toxicity, as well as biodegradability.78 This evidence concerns the gene ALB and cancer.
