α-lipoic acid is a naturally occurring compound with potent antioxidant properties that helps protect cells and tissues from oxidative stress. Its incorporation into nanoplatforms can affect factors like bioavailability, stability, reactivity, targeted delivery. Nanoformulations of significantly enhance its solubility absorption, making it more bioavailable. While be prone to degradation in free form, encapsulation within nanoparticles ensures stability over time, release controlled sustained manner the cells. In addition, combined other compounds, such as antioxidants, drugs, or nanomaterials, create synergistic effects their overall therapeutic benefits hinder potential cytotoxicity. This review outlines advantages drawbacks associated use acid, well various nanotechnological approaches employed effectiveness, whether alone combination bioactive agents. Furthermore, describes engineering produce poly(α-lipoic acid) nanoparticles, which hold promise an effective drug delivery system.

Metal adhesive synthesis typically involves heating and solvents, the resultant adhesives lack degradability suffer from recycling sustainable problems. Herein, we developed a solvent-free chemically degradable biobased (p(Elp-TA)+PVP) thioctic acid (TA), its derivative (Elp), polyvinylpyrrolidone (PVP). Through rapid acid-triggered cationic ring-opening polymerization of dithiolane at ambient conditions, p(Elp-TA)+PVP could build up strong lap shear strength 1123 kPa in air an underwater 534 to copper plate. Molecular dynamics simulations show that compared p(Elp-TA), presence appropriate amount PVP can significantly enhance binding energy molecules metal substrate, adhesion substrates was achieved through synergistically dynamic adaptive network enhanced by hydrogen bonding, reversible coordination bonding 40 ps. More importantly, applied be easily degraded reverted small-molecular-weight lipoic species. Upon exposure dithiothreitol, green reducing agent, average molecular weight quickly decrease 1603 kDa 274 Da. This constructed simple method provides promising general strategy for developing controlled recoverable natural resources.

Periodontitis is a chronic inflammatory condition driven by plaque-associated microorganisms, where uncontrolled bacterial invasion and proliferation impair host immune responses, leading to localized periodontal tissue inflammation bone destruction. Conventional therapies face challenges, including incomplete microbial clearance the rise of antibiotic resistance, limiting their precision effectiveness in managing periodontitis. Recently, nanotherapies based on polymeric materials have introduced advanced approaches antimicrobial therapy through diverse mechanisms. This review explored specific mechanisms, emphasizing design polymer-based agents that employ individual or synergistic actions, evaluated innovations limitations current strategies while forecasting future trends development for

Abstract Cisplatin‐induced ototoxicity is attributed to the aberrant accumulation of reactive oxygen species (ROS) within inner ear. Antioxidants represented by α‐lipoic acid (ALA) have been demonstrated scavenge ROS in cochlea, while effective delivery these agents vivo remains a major challenge. Here, novel polydopamine (PDA) nanogel decorated adhesive and responsive hierarchical microcarriers for controllable presented ALA deafness prevention. As composite exhibit excellent bioadhesion capabilities, this can result prolonged retention time allow precise under light stimulation, which significantly enhances therapeutic efficacy ALA. Based on features, both vitro experiments are that combined with near‐infrared irradiation effectively attenuate cisplatin‐induced ototoxicity. These findings suggest viable approach ear medication prevention deafness.

A new push-pull dye has been developed as a pH indicator when covalently copolymerized in lipoic acid-based polymer (LA-Py). Furthermore, various charged forms of the dyes are investigated antifouling diluents self-assembled monolayers (SAMs) on gold electrodes. The contain an amino donor incorporated into seven-membered heterocyclic disulfide ring, pyridine or pyridinium acceptor moiety, and oligo-phenylene ethylene (OPE) conjugated bridge. common characteristic is high sensitivity to solvent dipoles such Stokes shifts 176 211 nm for (Py) acetonitrile (MePy) chloroform, respectively. This coupled with decrease quantum yields increasing polarity solvents. LA-Py apparent pKa 3.5 showed acidic conditions robust cycling between 7 -0.08, producing average contrast 36% over 10 cycles. Incorporated SAM, zwitterionic sulfonate (SPy) derivative demonstrated BSA by continuous monitoring impedance electrochemical spectroscopy ionic permeability K3[FeCN6] cyclic voltammetry.
