A Natural Rubber–Based Adhesive Dressing Enriched With Rhodomyrtus tomentosa Leaf Extract Exhibiting Antioxidant, Anti-Inflammatory, and Antibacterial Activities Against Acne-Causing Bacteria

Advances in Pharmacological and Pharmaceutical Sciences
An acne treatment patch was developed by incorporating Rhodomyrtus tomentosa (RT) leaf extract into hyaluronic acid serum, followed by integration with high-quality block natural rubber using a two-roll milling process. RT hyaluronic acid serum exhibited

Tough and Skin‐Free Porous Polyelectrolyte Complex Hydrogels via Salt‐Induced Aqueous Phase Separation

Advanced Functional Materials, EarlyView.
Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...

Effects of aluminum oxide addition on the flexural strength, surface hardness, and roughness of heat-polymerized acrylic resin

Journal of Dental Sciences, 2012
Background/purpose: Acrylic dentures frequently fracture during service due to their poor strength characteristics. The aim of this study was to evaluate the effects of adding 0.5–5 wt% aluminum oxide (Al2O3) powder on the flexural strength, surface ...

Enzyme‐Loaded Fe3+‐Modified Polydopamine Microparticles: Bioreactor Systems for Operating Biocatalytic Cascades, Enantioselective Transformations and Sensor Applications

Advanced Functional Materials, EarlyView.
Enzyme‐loaded Fe3+‐modified polydopamine microparticles (Fe3+‐PD) act as hybrid biocatalytic frameworks demonstrating NADH peroxidase‐mimic catalytic activities, operation of biocatalytic cascades in confined media, and enantioselective oxidation of D/L‐DOPA. ABSTRACT We report on the synthesis of Fe3+‐modified porous polydopamine microparticles acting

Collagens as biomaterials

Journal of Materials Science: Materials in Medicine, 2008
This paper reviews the structure, function and applications of collagens as biomaterials. The various formats for collagens, either as tissue-based devices or as reconstituted soluble collagens are discussed. The major emphasis is on the new technologies that are emerging that will lead to new and improved collagen-based medical devices. In particular,

Nanodiamond Sensing in Dynamic Environments With Fast‐Tracking Through Four‐Point Positioning

Advanced Functional Materials, EarlyView.
A four‐point positioning tracking (4PPT) platform enables fast 3D feedback translational tracking of fluorescent nanodiamonds while simultaneously recording ODMR spectra. By integrating real‐time translational tracking with quantum sensing, mobile nanodiamonds are used for in‐situ nanothermometry, nanorheometry, and 6D translation–rotation tracking in ...

Membranes as Biomaterials [PDF]

Polymer Journal, 1991
Five different artificial organs or tissues are selected from our studies to show how membranes are used as biomaterials. They are artificial kidney, artificial lung, artificial skin, artificial pancreas, and artificial cornea. The membranes in these artificial organs are mostly employed to allow the selective permeation of some substances, similar to ...

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed
