Advanced technology in pharmaceutical science has encouraged the development of various applications of biomaterials in drug delivery. Zein, a plant protein, has attracted the interest of a number of researchers for applications in pharmaceutical technology, including solid dispersions, tablets, nanoparticles, microparticles, film coatings, powders, and gels. Diverse strategies for the use of zein for controlled drug release have been investigated and reported in the literature, especially engineering strategies for using zein conjugates to enhance oral bioavailability and targeted delivery, which has attracted interest in recent research. Although still limited, the ability to fabricate self-assembling nanoparticles loaded with molecules of interest offering functional groups for potential conjugation could yield zein-based conjugates with promise as materials for drug delivery. In the current review, recent studies of zein-based conjugates with outstanding features are discussed based on the various types of conjugation. The key physicochemical characterization methods for the chemical conjugation and identification of zein will be summarized. Further opportunities to develop zein-based materials through conjugation will provide promising alternative formulations for a number of drug candidates.

Systems for the delivery of drugs to target sites of pharmacological actions. Technologies employed include those concerning drug preparation, route of administration, site targeting, metabolism, and toxicity.
Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.
Nanometer-sized particles that are nanoscale in three dimensions. They include nanocrystaline materials; NANOCAPSULES; METAL NANOPARTICLES; DENDRIMERS, and QUANTUM DOTS. The uses of nanoparticles include DRUG DELIVERY SYSTEMS and cancer targeting and imaging.
The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis.
Artificial, single or multilaminar vesicles (made from lecithins or other lipids) that are used for the delivery of a variety of biological molecules or molecular complexes to cells, for example, drug delivery and gene transfer. They are also used to study membranes and membrane proteins.
