Albumin/Hyaluronic Acid Nanoparticle-Laden Contact Lenses for the Ocular Delivery of 5-Fluorouracil.

Nanoparticle-laden contact lenses are a formidable strategy for ocular drug delivery. However, incorporating nanoparticles to achieve sustained drug release without affecting the contact lenses' properties remains a challenging task. In this work, daily and monthly replacement silicone-hydrogel contact lenses laden with bovine serum albumin/hyaluronic acid (BSA/HA) nanoparticles are presented.

Cryogels Composites: Recent Improvement in Bone Tissue Engineering.

Autogenous bone grafts have long been considered the optimal choice for bone reconstruction due to their excellent biocompatibility and osteogenic properties. However, their limited availability and associated donor site morbidity have led to exploration of alternative bone substitutes. Cryogels, with their interconnected porosity, shape recovery, and enhanced mass transport capabilities, have emerged as a promising polymer-based solution.

Multifunctional magneto-plasmonic lipogel based on peptide hydrogel for application in combined cancer therapy.

Supramolecular hydrogels, particularly low-molecular-weight peptide hydrogels, are promising drug delivery systems due to their ability to change the solubility, targeting, metabolism and toxicity of drugs. Magneto-plasmonic liposomes, in addition to being remotely controllable with the application of an external magnetic field, also increase the efficiency of encapsulated drug release through thermal stimulation, for example, with magnetic and optical hyperthermia. Thus, the combination of those two materials-giving magneto-plasmonic lipogels-brings together several functionalities, among which are hyperthermia and spatiotemporally controlled drug delivery.
