We report a facile method to synthesize Fe3O4@polydopamine (PDA)-Ag core-shell microspheres. Ag nanoparticles (NPs) are deposited on PDA surfaces via in situ reduction by mussel-inspired layers. High catalytic activity and fast adsorption of model dye methylene blue (MB) at different pH values achieved mainly due the presence monodisperse NPs electrostatic interactions between MB. The as-prepared Fe3O4@PDA-Ag microspheres also show high cyclic stability (>27 cycles), good acid stability,...
We describe a synthetic method for increasing and controlling the iron loading of melanin nanoparticles use resulting materials to perform systematic quantitative investigation on their structure–property relationship. A comprehensive analysis by magnetometry, electron paramagnetic resonance, nuclear magnetic relaxation dispersion reveals complexities behavior how these intraparticle interactions manifest in useful material properties such as performance MRI contrast agents. This allows...
We report the preparation and study of Mn(III)-, Fe(III)-, Co(II)-, Ni(II)-, Cu(II)-, Zn(II)-, Ga(III)-loaded polydopamine nanoparticles (PDA-NPs) via autoxidation polymerization metal–dopamine complexes in presence free dopamine. An analysis doping range parameters that influence final particle morphology is presented. In addition, magnetometry provides a probe general electronic structure interactions for Co(II)-loaded PDA-NPs. PDA-NPs doped with Mn(III) are found to have high spin, low...
Stimuli-responsive multifunctional mesoporous silica nanoparticles (MSNs) have been studied intensively during the past decade. A large variety of mesopore capping systems designed, initially to show that it could be done and later for biomedical applications such as drug delivery imaging. On-command release cargo molecules drugs from pores can activated by a stimuli. This paper focuses on three noninvasive, biologically usable external stimuli: magnetism, ultrasound, light. We survey MSNs...
Synthetic melanin is a mimic of natural analogue with intriguing properties such as metal–ion chelation, redox activity, adhesion, and broadband absorption. Melanin-inspired composite materials are formulated by assembly other types inorganic organic components to target, combine, build up the functionality, far beyond their capabilities. Developing efficient universal methodologies prepare melanin-based unique functionality vital for further applications. In this review, we summarize three...
Mussel-inspired polydopamine catalyst carriers dramatically enhance the catalytic performance (∼450%) of Au nanoparticles in methylene blue reduction, which is attributed to local enrichment mechanism caused by favourable attractive interaction between and reactants.
Amphiphilic triblock copolymers containing Fe III ‐catecholate complexes formulated as spherical‐ or cylindrical‐shaped micellar nanoparticles ( SMN and CMN , respectively) are described new T 1 ‐weighted agents with high relaxivity, low cytotoxicity, long‐term stability in biological fluids. Relaxivities of both exceed those established gadolinium chelates across a wide range magnetic field strengths. Interestingly, shape‐dependent behavior is observed terms the particles' interactions HeLa...
Polyacrylic pressure-sensitive adhesives (PSAs) based on butyl acrylate (BA), 2-hydroxyethyl (HEA), and acrylic acid (AA) were prepared by a bulk polymerization process triggered radical photoinitiator under UV irradiation UV-crosslinking. 1,6-Hexanediol diacrylate (HDDA) with difunctional groups was introduced into the PSAs to modify semi-interpenetrating network structures. The effect of HDDA content performance comprehensively tested. viscosity prepolymer measured rotational viscometer....

Here, we describe a biocompatible multifunctional silica-iron oxide nanoparticle to help solve these issues. The nanoparticles were made via an situ growth of Fe3O4 on both the external surfaces pore walls mesocellular foam silica nanoparticles. In contrast previous work, this approach builds magnetic moiety inside pores porous structure. These materials serve three roles: drug delivery,...
Photothermal therapy combined with chemotherapy has shown great promise in the treatment of cancer. In this synergistic system, a safe, stable, and efficient photothermal agent is desired.

Bacterial infections in wounds and bacteremia present significant global health challenges, driving the urgent need for innovative alternatives to traditional antibiotics. Here, development of PEI-EDTA-2Na carbon quantum dots (PECDs) synthesized via a hydrothermal method is reported. Synthesis conditions affect PECDs' antibacterial efficacy; those at 180 °C have optimal -NH2 functionalization better adhesion activity. PECDs are pH - responsive, eradicating bacteria weakly acidic by...
