Implant-integrated drug delivery systems that enable the release of biologically active factors can be part of an in situ tissue engineering approach to restore biological function. Implants can be functionalized with drug-loaded nanoparticles through a layer-by-layer assembly. Such coatings can release biologically active levels of growth factors.

Drug loaded microfiber scaffolds have potential for sublingual drug delivery due to their fast dissolution time and tunable porosity. Such microfiber scaffolds can be prepared by melt electrowriting (MEW), wherein a polymer melt is electrostatically drawn out of a syringe onto a computer controlled moving collector. The fabrication of such scaffolds via MEW has previously been shown for a polymer with a glass transition temperature (T) just above room temperature, making handling challenging.

Objectives: Drug-loaded mucoadhesive silk fibroin (SF) microneedle patch can overcome the limitations of low bioavailability and significant pain associated with traditional treatment methods, such as topical application or injection of triamcinolone for oral submucous fibrosis (OSF). However, these systems release the drug too quickly, failing to meet the clinical requirements. This study aims to construct a mucoadhesive SF microneedle patch pre-assembled with silk fibroin nanospheres (SFN) and explore its ability to sustain the release of triamcinolone in the treatment of OSF.

The present study aimed to explore an ideal delivery system for triptolide (TPL) by utilizing the thin-film hydration method to prepare drug-loaded, folate-modified mixed pluronic micelles (FA-F-127/F-68-TPL). Scanning electron microscopy and atomic force microscopy showed that the drug-loaded micelles had a spherical shape with a small particle size, with an average of 30.7 nm.
