Unwanted nonspecific adsorption caused by biomolecules influences the lifetime of biomedical devices and sensing performance biosensors. Previously, we have designed B-M-E triblock proteins that rapidly assemble on inorganic surfaces (gold silica) render those antifouling. The a surface-binding domain B, multimerization M an antifouling E. Many technologies involve organic (polymeric) where could potentially be used. In this study, computationally experimentally investigate assembly polystyrene (PS) surfaces, using PS-binding peptides as block B. We used atomic force microscopy, dynamic light scattering, fluorescence microscopy quartz crystal microbalance to test coating functionality. found that, like for with B block, form homogeneous monomolecular layers PS good stability against PBS washing. adsorbed protein layer fully prevents fluorescently labeled bovine serum albumin microfluidic chips. Similarly, no significant fouling was observed when 1 % (v/v) or 10 human were foulants.

Durable Organic Coating‐Free Superhydrophobic Metal Surface by Paracrystalline State Formation

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 30, 2024

Abstract The chemical instability of traditional organically‐decorated superhydrophobic metal surfaces is a significant issue, severely limiting practical applications. This due to the susceptibility low surface energy coatings ion permeation, decomposition, and exfoliation, especially in harsh environments. Here, organic coating‐free, durable on Al alloys by developing paracrystalline state bionic anthill tribe structure successfully achieved, using femtosecond laser element‐doping microstructuring followed repetitive annealing processes. Remarkably, inherent properties sample are maintained for ≈2000 h corrosive 3.5 wt.% NaCl aqueous solution, significantly surpassing performance coatings. Moreover, this superhydrophobicity remains nearly unchanged, even after rigorous electrochemical reaction measurements. Additional tests involving UV irradiation (>100 h), freezing cycles cycles), acid/alkali resistance (>65 h) further demonstrate that environmental adaptability far exceeds silane‐coated surfaces. Ab initio calculations reveal formation reduces enhances stability, thereby extending durability metal. These findings offer powerful strategy utilizing atomic‐level structural rearrangements design without need

Self‐Regenerating Zwitterionic Hydrogel Coating Modified by Metal‐Organic Framework for Integrated Anti‐Biofouling and Anti‐Corrosion

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 10, 2025

Abstract Hydrogel coating has a certain ability to inhibit marine biofouling. However, owing their poor mechanical properties and short service life, they have not found solid applications in protection. Herein, novel self‐regenerating zwitterionic hydrogel composed of self‐crosslinking degradable polymer with hydrolysis‐induced zwitterions corrosion inhibitor benzotriazole (BTA) loaded metal‐organic framework (MOF) is reported, which exhibits both anti‐biofouling anti‐corrosion performance. The prepared by copolymerization 2‐methylene‐1,3‐dioxepane (MDO) vinyl chloroacetate (VCA) followed grafting 2‐(trimethoxysilyl) propyl dimethylamino propionate (TPD). It can self‐crosslink or crosslink BTA‐loaded MOF forming network, even chemically link the substrate creating robust interface. Accordingly, good adhesion. Because surface antifouling be continuously renewed degradation hydrolysis polymer, high resistance bacteria diatom seawater. also enable release BTA, significantly inhibiting corrosion. This study represents an important step toward integration into coating.
