We developed prodrug nanoparticles that release drugs through intracellular dissolution and a cancer-specific hydrogen peroxide response. To reveal the unclear mechanism regarding drug release from nanoparticles by reacting with hydrogen peroxide in cancer cells, this study demonstrates the evaluation of drug release kinetics under conditions simulated in cancer cells.

Many brain-targeting drug delivery strategies have been reported to permeate the blood-brain barrier (BBB) via hijacking receptor-mediated transport. However, these receptor-based strategies could mediate whole-brain BBB crossing due to the wide intracranial expression of target receptors and lead to unwanted accumulation and side effects on healthy brain tissues. Inspired by brain metastatic processes and the selectivity of brain metastatic cancer cells for the inflammatory BBB, a biomimetic nanoparticle was developed by coating drug-loaded core with the inflammatory BBB-seeking erythrocyte-brain metastatic hybrid membrane, which can resist homotypic aggregation and specially bind and permeate the inflammatory BBB for specific drug delivery.

Recently, cancer therapy has witnessed remarkable advancements with a growing focus on precision medicine and targeted drug delivery strategies. The application of anionic polysaccharides has gained traction in various drug delivery systems. Anionic polysaccharides have emerged as promising delivery carriers in cancer therapy and theranostics, offering numerous advantages such as biocompatibility, low toxicity, and the ability to encapsulate and deliver therapeutic agents to tumor sites with high specificity.

Traditional wound closure methods often present several issues, including additional puncture wounds, adverse effects from anesthesia, and noticeable scarring. Inspired by embryonic wound healing, a Janus hydrogel (PG/Au-Asp@PCM) is designed to manipulate non-invasive wound closure by photothermal-responsive self-contraction of PG/Au-Asp@PCM, which is attributed to the shape memory behavior of PG/Au-Asp@PCM under near-infrared (NIR). Wherein, gelatin acts as a thermally reversible "switch" and polyacrylamide creates stable and cross-linked "net-points".

Chlorhexidine (CHX) is a gold standard therapeutic agent against clinical oral pathogens. However, its oral use is limited due to unpleasant taste, alteration in taste buds, staining of teeth and mucous membranes. Therefore, CHX-loaded PLGA microneedles (MNs) were fabricated for local and controlled release in the oral cavity, using a casting mold method.

Poly(DL-lactide-co-glycolide) (PLGA) and N-methyl-2-pyrrolidone (NMP)-based in situ forming implants are liquid formulations that solidify through phase separation following injection into the body. Drug is dissolved or suspended in the final formulation liquid prior to injection. Depending on the polymers used, the depots formed can deliver drug over different periods of time.
