Polymeric zein nanoparticles (ZNP), derived from corn protein, are biodegradable drug carriers with high stability and low synthesis costs. Their amphiphilic nature allows efficient encapsulation of both hydrophilic and lipophilic drugs, making them promising for drug delivery. However, their instability under physiological pH can limit therapeutic efficacy, necessitating protective coatings for improved absorption. This review discusses synthesis methods, coating materials, and biological activities of bioactive-coated ZNP. We found that the antisolvent method is the most commonly used due to its simplicity and cost-effectiveness, while chitosan is the preferred coating material. ZNP exhibit antioxidant, anticancer, anesthetic, antidiabetic, hypoglycemic, and immunogenic properties, as demonstrated in both in vitro and in vivo studies. Their ability to enhance bioavailability, reduce toxicity, and enable targeted drug delivery highlights their potential in nanomedicine.
