The release behavior of a model compound (β-naphthol orange) encapsulated in (meth)acrylate-based statistical copolymers under different environmental conditions was investigated. From monomers of varying polarity (methyl acrylate, ethyl acrylate, tert-butyl acrylate, 2-ethylhexyl methacrylate, and benzyl methacrylate) in combination with methacrylic acid, five polymer series were synthesized by free radical polymerization. The pH-dependent release kinetics were investigated via UV-vis spectroscopy at pH 1.2 and 6.8, simulating physiological conditions in the stomach and intestines. Furthermore, the influence of different ethanol contents (0 and 40 vol %) in the acidic medium was investigated. The whole approach was designed to meet the requirements of a high-throughput experimentation workflow.

Chemotherapeutic drugs often fail to provide long-term efficacy due to their lack of specificity and high toxicity. To enhance the biosafety and reduce the side effects of these drugs, various nanocarrier delivery systems have been developed. In this study, we loaded the anticancer drug doxorubicin (DOX) and an MRI contrast agent into silica nanoparticles, coating them with pH-responsive and tumor cell-targeting polymers.

Smart textiles that integrate multiple environmental sensing capabilities are an emerging frontier in wearable technology. In this study, we developed dual pH- and temperature-responsive textiles by combining engineered bacterial systems with bacterially derived proteins. For temperature sensing, we characterized the properties of a heat sensitive promoter, P, in () using enhanced green fluorescent protein as a reporter.

Next-generation wound dressings with multiple biological functions hold promise for addressing the complications and pain associated with burn wounds. A hydrogel wound dressing loaded with a pain-relieving drug was developed for treating infected burn wounds. Polyvinyl alcohol chemically grafted with gallic acid (PVA-GA), sodium alginate chemically grafted with 3-aminobenzeneboronic acid (SA-PBA), Zn, and chitosan-coated borneol nanoparticles with anti-inflammatory and pain-relieving activities were combined to afford a nanoparticle-loaded hydrogel with a PVA-GA/Zn/SA-PBA network crosslinked via multiple physicochemical interactions.

Liver fibrosis is a common pathological stage in the development of several chronic liver diseases, and early intervention can effectively reverse the developing process. Excessive reactive oxygen species (ROS) can promote the activation of hepatic stellate cells (HSCs), but existing treatments have not addressed this problem. In this study, different metal-based mesoporous polydopamine (MPDA) was prepared by the soft template method, and their free radical scavenging abilities, as well as the efficacy and safety of the carriers were investigated, so as to select Cu-coordinated MPDA (CMP) as the optimal nanocarrier.

Anticounterfeiting technologies have become increasingly crucial due to the growing issue of counterfeit goods, particularly in high-value industries. Traditional methods such as barcodes and holograms are prone to replication, prompting the need for advanced, cost-effective, and efficient solutions. In this work, a practical application of anodic aluminum oxide (AAO) membranes are presented for anticounterfeiting, which addresses the challenges of high production costs and complex fabrication processes.
