pH‐Responsive Sodium Alginate Micro‐Nano Hydrogels for Oral Insulin Delivery: Enhancing Therapeutic Efficacy and Reducing Hypoglycemic Risk

open access: yesFood Frontiers, EarlyView.
Schematic illustration of pH‐responsive SC@AP@INS for oral insulin delivery. (A) pH‐responsive mechanism of sodium alginate‐based hydrogels. (B) Preparation of drug‐loaded microsphere gel via the electrospray method. The controlled release of drug‐loaded micelles in the colon enhances insulin delivery efficiency while minimizing systemic exposure and ...

An Optimized Staining Method for Visualization of Thermally Denatured Dermal Collagen

open access: yesLasers in Surgery and Medicine, EarlyView.
ABSTRACT Background and Objectives Accurate visualization of thermal damage zone (TDZ) in the dermis is critical for energy‐based device (EBD) and burn research. While nitroblue tetrazolium chloride (NBTC) staining and birefringence imaging are commonly used, both rely on detecting loss‐of‐signal, thereby only inferring TDZ indirectly.

Bio‐Inspired, Zwitterionic Copolymers with Amphiphilic Character

open access: yesMacromolecular Rapid Communications, EarlyView.
Zwitterionic copolymers based on arginine‐derived monomers are produced by xanthate‐supported photo‐iniferter reversible‐addition‐fragmentation chain‐transfer polymerization. Experiments in relevant conditions show that the designed (co)polymers hardly interact with biologically relevant proteins and enzymes such as bovine serum albumine (BSA), fetal ...

Ex Vivo Evaluation of Poly(Solketal Acrylate) Nanoparticles for Intravitreal Drug Delivery to the Posterior Eye Segment

open access: yesMacromolecular Rapid Communications, EarlyView.
Nile Red‐loaded poly(solketal acrylate) nanoparticles enable fluorescence tracking and exhibit nontoxic profiles in retinal cells. Enhanced cellular uptake and deep retinal penetration after intravitreal injection highlight their excellent potential for targeted ocular drug delivery to the posterior segment of the eye.

Ion-associated Complex of the Anionic Chelate of Germanium(IV) with Nitro Derivative of the Catechol and the Cation of Monotetrazolium Salt

open access: yesActa Chimica Slovenica, 2019
The formation of an ion-associated complex between of the anionic chelate of germanium(IV) with 4-nitrocatechol (4-NC) and the cation of 3-(2-naphtyl)-2,5-diphenyl-2H-tetrazolium chloride (TV) was investigated by spectrophotometry. The optimum conditions

Toward Dynamic Liquid Cell Scaffold: Photoreversible Ion Gels Exhibiting Light‐Induced Sol‐Gel Transitions

open access: yesMacromolecular Rapid Communications, EarlyView.
Light‐programmable, non‐cytotoxic ion gels based on ABC triblock copolymers undergo photoreversible sol‐gel transitions, crossing the rheological boundary (tan δ ∼ 1). UV–vis light irradiation modulates the lifetime of reversible junctions, switching the scaffold between liquid‐like and solid (gel)‐like states.

Crosslinked Gelatin‐Polycaprolactone Scaffolds: Balancing Biocompatibility and Inflammatory Response for Tissue Engineering Applications

open access: yesPolymer Engineering &Science, EarlyView.
Crosslinked gelatin‐functionalized PCL scaffolds exhibited enhanced hydrophilicity, structural stability, and porous interactions. In vitro assays demonstrated improved osteoblast adhesion, viability, and proliferation without cytotoxicity, while in vivo evaluation showed no adverse inflammatory response, supporting their potential application in ...
