Development of new types antibacterial coatings or nanocomposites is great importance due to widespread multidrug-resistant infections including bacterial infections. Herein, we investigated biocompatibility as well structural, photocatalytic, and properties photoactive hydrophobic carbon quantum dots/polyurethane nanocomposite. The swell-encapsulation-shrink method was applied for production these nanocomposites. Hydrophobic were found be highly effective generator singlet oxygen upon...
Inimitable properties of carbon quantum dots as well a cheap production contribute to their possible application in biomedicine especially antibacterial and antibiofouling coatings. Fluorescent hydrophobic are synthesized by bottom-up condensation method used for deposition uniform homogeneous Langmuir–Blodgett thin films on different substrates. It is found that this kind generates singlet oxygen under blue light irradiation. Antibacterial testing four bacteria strains (Escherichia coli,...
The addition of heteroatoms to pristine carbon quantum dots (CQDs) change their structure and optical properties. In this study, fluorine (F)- chlorine (Cl)-doped CQDs are prepared by the one-step green hydrothermal route from sodium fluoride, chloride, urea, citric acid as starting precursors. Microscopy analysis reveals that average size these is 5 ± 2 nm, whereas chemical study shows existence C–F C–Cl bonds. produced F- Cl-doped have fluorescence yields 0.151 0.284, respectively, at an...
Due to controversial reports concerning antibacterial activity of different graphene based materials it is very important investigate their action on a wide range Gram-positive and Gram-negative bacteria. In this paper we have investigated the structure induced phototoxic four types materials: oxide (GO), quantum dots (GQDs), carbon (CQDs) nitrogen doped (N-CQDs). Antibacterial was tested 19 It found that nanometer-size CQDs N-CQDs are most potent agents whereas micrometer-size GO has poor...
Polyethylene (PE) is one of the most widely used polymers in many industrial applications. Biomedical uses seem to be attractive, with increasing interest. However, PE it prone infections and its additional surface treatment indispensable. An increase resistance can achieved by treating surfaces substances containing antibacterial groups such as triclosan (5-Chloro-2-(2,4-dichlorophenoxy)phenol) chlorhexidine (1,1'-Hexamethylenebis[5-(4-chlorophenyl)biguanide]). This work has examined impact...
Development of new types antimicrobial coatings is utmost importance due to increasing problems with pathogen transmission from various infectious surfaces human beings. In this study, highly potent polyurethane composite films encapsulated by hydrophobic riboflavin-based carbon polymer dots are presented. Detailed structural, optical, antimicrobial, and cytotoxic investigations these composites were conducted. Low-power blue light triggered the eradicate Escherichia coli in 30 min, whereas...
Silicone elastomers are commonly cured by hydrosilylation or condensation reactions, both of which require metal-based catalysts. Due to environmental, toxicological, and cost concerns, there is considerable interest in developing metal-free alternatives. Herein, we present a novel solution via an atom-efficient, catalyst-free ring-opening poly(2-isopropenyl-2-oxazoline) (PiPOx) as curing agent. PiPOx macromolecules bearing pendant reactive 2-oxazoline groups capable undergoing reaction the...
Graphene oxide can be reduced by tertiary amine in one step during ATRP to directly obtain conductive hybrids and/or composites.
Silk fibroin is a biocompatible, non-toxic, mechanically robust protein, and it commonly used studied as material for biomedical applications. also gained particular interest drug carrier vehicle, numerous silk formats have been investigated this purpose. Herein, we prepared electrospun nanofibers from pure blended fibroin/casein, followed by the incorporation of an anti-inflammatory drug, diclofenac. Casein serves excipient in pharmaceutical products has positive effect on gradual release...
The utilization of keratin waste in new materials formulations can prevent its environmental disposal problem. Here, novel composites based on biodegradable blends consisting poly(lactic acid) (PLA) and poly(3-hydroxybutyrate) (PHB), filled with hydrolyzed loading from 1 to 20 wt % were prepared their properties investigated. Mechanical viscoelastic characterized by tensile test, dynamic mechanical thermal analysis (DMTA) rheology measurements. addition acetyltributyl citrate (ATBC)...
Abstract Novel alginate-based binders containing either catechol (d-Alg) or sulfonate (s-Alg) functional groups were developed and characterized to improve the capacity decay performance better stability of Li-ion batteries. The electrochemical silicon–graphite (Si/Gr) anode with compared commonly used CMC/SBR binder. active material in anodes was ball-milled Si/Gr (20:80 wt%) powder mixture. A comprehensive study carried out through rate capability test, cycle differential analysis (d Q /d...
Abstract The surface and adhesive properties of isotactic polypropylene (iPP) grafted by maleic anhydride (MA) have been investigated. attention has paid to the analysis change in hydrophilicity as well interfacial equilibrium mechanical work adhesion MA iPP copolymer (iPP‐ g ‐MA) containing various level MA. energy iPP‐ ‐MA increases with level. value joint polyvinyl acetate (PVAc) decreases. PVAc significantly growing content ‐MA, mainly its polar component. enhances well. shear strength...
