Zein, a maize-derived protein, is increasingly utilized in nanoparticle delivery systems due to its biocompatibility and biodegradability. This study aimed to review the latest progress in fabricating, structure designing, characterizing, and functions associated with nanoparticles based on zein. Key fabrication techniques and their impacts on the nanoparticle properties were examined. Different structural designs of zein nanoparticles, including composite, core-shell, and layer-by-layer assembled configurations, were highlighted. The roles exerted by these nanoparticles in delivering, protecting, and regulating the release of bioactive substances were also investigated. Fabrication methods influenced the nanoparticle size, morphology, and stability, which, in turn, affected the encapsulation and release efficiency of bioactive compounds. Additionally, various structural designs improved the stability of zein nanoparticles, controlled the release of bioactive compounds, and enabled the personalization of multiple bioactive compounds. These findings highlight the potential of zein-based nanoparticles as efficient carriers for functional compounds, offering enhanced stability, bioavailability, and targeted release.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
The table below summarizes some of the major functional groups in organic chemistry.
Structural Protein Function
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

Structure and Function of Erythrocytes
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
