Tragacanth is a nontoxic, biodegradable and biocompatible polymer applied as a nanostructure form in various fields such as biomedicine and food industry. Here, hydrogel Tragacanth nanofibers were fabricated using a modified microemulsion method. The effective parameters on the fabrication of nanofibers such as emulsifier type, stirrer type, processing time and concentrations of emulsifier, Tragacanth and aluminum chloride were studied and the conditions were optimized for high quality nanofibers. SEM images indicated Tragacanth nanofiberswere successfully synthesized with average diameter of 50 nm and uniformdistribution. Appear a peak at 1110 cm related to Al-C bonds and reduce intensity ofthe peaks at 1742 and 1629 cm and in FT-IR spectrum of nanofibersprove the successfully synthesis. Further, the hydrogel properties of the synthesized nanofibers can be proved by the swelling of 142% and drying time of 3 h.

Resins are complex mixtures of natural constituents containing non-volatile and volatile terpenes, in combination with gums and polyphenols, used since ancient times for their medicinal properties. Current research has evidenced their therapeutic value with a plethora of activities. The main limits of resins and their constituents for their clinical use are low water solubility, poor stability and bioavailability.

The rising incidence of fungal infections, compounded by the emergence of severe antifungal resistance, has resulted in an urgent need for innovative antifungal therapies. We developed an antifungal protein-based formulation as a topical antifungal agent by combining an artificial lipidated chitin-binding domain of antifungal chitinase (LysM-lipid) with recently developed ionic liquid-in-oil microemulsion formulations (MEFs). Our findings demonstrated that the lipid moieties attached to LysM and the MEFs effectively disrupted the integrity of the stratum corneum in a mouse skin model, thereby enhancing the skin permeability of the LysM-lipids.

Nanotechnology has gained recognition as the next uprising technology in numerous sectors, together with food industry and agriculture. Diminution of particle size to nanoscale range enhances the surface area, eventually surface-to-volume ratio, subsequently enhances their reactivity by several times, modifying optical, electrical, and mechanical features. Nanotechnology can also modify the aqueous solubility, thermal stability, and bioavailability in oral delivery of bioactive nutraceuticals.

Research on hydroxyapatite (HAP) coatings for bone tissue applications has been investigated for decades due to their significant osteoconductive and bioactivity properties. HAP closely resembles the mineral component of human bone, making it ideal for biomedical applications such as implants. This study investigates the synthesis of hydroxyapatite nanoparticles (HAP-NPs) via the microemulsion method, which is essential for creating HAP coatings on the Ti-6Al-4V substrate.

The intestinal mucus layer plays a crucial role in the systemic absorption of drugs. While penetration through this layer traditionally constitutes a pivotal phase in drug absorption, the approach for treating ulcerative colitis (UC) shifts towards facilitating the direct delivery of drugs to the colon. In this study, we engineered a chitosan-modified microemulsion encapsulated nobiletin (NOB-CS-ME) characterized by small particle dimensions and positive charge specifically, designed to enable targeted delivery.
