Cross-Linked Polymer Brushes Containing -Halamine Groups for Antibacterial Surface Applications.

Microbial contamination is a significant issue in various areas, especially in the food industry. In this study, to overcome microbial contamination, cross-linked polymer brushes containing -halamine were synthesized, characterized, and investigated for antibacterial properties. The cross-linked polymer brushes with different -halamine ratios were synthesized by in-situ cross-linking methods with reversible addition-fragmentation chain transfer (RAFT) polymerization using a bifunctional cross-linker.

A switchable polymer brush system for antifouling and controlled detection.

A stimuli-responsive polymer brush system is designed to switch on and off surface functionality and prevent functional groups from fouling by grafting together two polymer brushes with precisely controlled lengths. The polymer brush with functional groups has a fixed length, while the other brush extends and collapses as the environment changes.

Synthesis, structure characterization and antimicrobial evaluation of 4-(substituted phenylazo)-3,5-diacetamido-1H-pyrazoles.

The present article deals with the synthesis, spectral characterization and antimicrobial activity of phenylazo dyes. All of the synthesized phenylazo dyes were characterized using ATR-FTIR, FT-Raman, (1)H NMR, (13)C NMR, elemental analysis and mass spectroscopic techniques. Solvent effects on the UV-Vis absorption spectra of these phenylazo dyes were studied.

Surface chemical conversion of 3-glycidoxypropyldimethylethoxysilane on hydroxylated silicon surface: FT-IR, contact angle and ellipsometry analysis.

The chemical conversion of the top surface of 3-glycidoxypropyldimethylethoxysilane (GPDMES) on hyroxylated silicon surface has been studied as a function of reaction time. A multiple-step procedure was applied in this study. At first, GPDMES molecules were self-assembled on the hydroxylated silicon surface.
