Gum Arabic is a natural dried exudate obtained from specific Acacia trees, composed primarily of polysaccharides and glycoproteins. Traditionally valued in the food and pharmaceutical sectors as an emulsifier and stabiliser, it exhibits biocompatibility, hydrophilicity, and intrinsic antibacterial properties. The natural polymer possesses numerous functional groups that allow for chemical modification, grafting, and cross-linking to introduce new material characteristics. Recent developments have engineered Gum Arabic into advanced formats such as nanoparticles, hydrogels, nanofibers, membranes, and scaffolds. These advanced formulations show promise across diverse fields, extending beyond conventional processing aids into biomedical roles such as cancer therapy, tissue regeneration, wound healing, biosensing, and bioimaging. Furthermore, they offer utility in industrial contexts, notably in protective food packaging and the creation of antimicrobial and antifouling membranes.
Gum Arabic is an established agricultural commodity currently used mostly as a simple additive. Demonstrating that its chemical structure allows conversion into high-value nanomaterials and biomedical devices could expand its economic utility. This provides opportunities to replace synthetic polymers with a biocompatible, natural alternative in critical sectors such as healthcare diagnostics, active therapeutics, and sustainable packaging.
The work indicates application pathways for developers in pharmaceutical formulation, medical devices, water filtration, and food packaging. Potential products include drug-delivery nanoparticles, wound dressings, and barrier films. Because the abstract outlines a broad review of potential uses rather than testing a specific commercial prototype, these advanced applications currently appear to sit at an early to intermediate stage of research and formulation design.

Gum Arabic (GA), or acacia gum, refers to the dried exudate produced by certain Acacia trees. GA is composed mainly of a mixture of polysaccharides and glycoproteins, with proportions that can slightly differ from one species to another. It is commonly utilized in the food and pharmaceutical industries as a stabilizer or an emulsifier owing to its biocompatibility, hydrophilicity, and antibacterial properties. In addition, GA can be manipulated as it possesses many functional groups that can be used in grafting, cross-linking, or chemical modifications to add a new feature to the developed material. In this review, we highlight recent GA-based formulations, including nanoparticles, hydrogels, nanofibers, membranes, or scaffolds, and their possible applications in tissue regeneration, cancer therapy, wound healing, biosensing, bioimaging, food packaging, and antimicrobial and antifouling membranes.
