Raising the concept of mucoadhesion in the 1980s, the use of mucoadhesive polymers for
buccal drug delivery has been the subject of interest. Buccal route is one of the non-invasive …

Chitosan, a natural biodegradable polymer, is of great interest in biomedical research due to
its excellent properties including bioavailability, nontoxicity, high charge density, and …

A natural long-chain polymer, chitin is the main component of the cell walls of fungi, the
exoskeletons of arthropods (including crustaceans and insects), the radulas of mollusks, and …

Introduction: Chitosan is the second most abundant natural polysaccharide. It belongs a
family of polycationic polymers comprised of repetitive units of glucosamine and N …

We derivatized low molecular weight chitosan (LMWC) with 3‐mercaptopropanoic acid (3‐
MPA) by a coupling reaction. The chemical modification of LMWC was characterized by …

We report the significant effect of intermolecular hydrogen bonding (H-bonding) on surface-
enhanced Raman scattering (SERS) spectra in which the vibrational frequencies and …

Oral delivery is considered the favoured route of administration for both local and systemic
delivery of active molecules. Formulation of drugs in conventional systems and …

Chitosan on its own is a well-established natural polymer and is widely regarded as a
biodegradable, biocompatible and nontoxic material for drug delivery applications. Although …

Polysaccharides constitute over 90% of the carbohydrate mass in nature, which makes them
a promising feedstock for manufacturing sustainable materials. Polysaccharide particles …

Objective: The aim of study was to investigate whether cell-penetrating peptides could
amplify cellular uptake of plasmid DNA (pDNA) loaded self-nanoemulsifying drug delivery …
