Nanostructured Single Crystals Sandwiched between Ordered/Disordered Coily and Rod Brushes [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2018
Single crystals of poly(ethylene glycol) (PEG)-b-polystyrene (PS), PEG-b-poly(methyl methacrylate) (PMMA), PEG-b-polycaprolactone (PCL), and polyaniline (PANI)-b-PEG-b-PANI were developed from dilute solutions and thin molten films using self-seeding ...

Electrochemical Studies Based on Local Interfacial pH Changes of Gold Nanoparticles Immobilized on Polystyrene Brushes

open access: yesInternational Journal of Electrochemical Science, 2013
The electrochemical behavior of polystyrene modified with gold nanoparticle (Au NPs) was investigated in terms of pH-responsive polymer brush. A pH-responsive of modified polymer brush from tethered polystyrene was prepared and used for selective gating ...

Strongly charged polymer brushes [PDF]

open access: yesEurophysics Letters (EPL), 2006
Charged polymer brushes are layers of surface-tethered chains. Experimental systems are frequently strongly charged. Here we calculate phase diagrams for such brushes in terms of salt concentration n_s, grafting density and polymer backbone charge density.

Interface Effects in Ultrathin Silicon on Insulator Films

open access: yesAdvanced Functional Materials, EarlyView.
This work establishes a systematic framework to discriminate how bulk and interface phenomena affect charge transport in ultrathin P‐doped silicon‐on‐insulator (SOI) films. For Si films below 15 nm, electrical characterization demonstrates that interface states drive charge transport, shifting the metal‐insulator transition (MIT) critical dopant ...

Functionalized Antifouling Polymer Brushes for Biospecific Surfaces

open access: yesAdvanced Materials Interfaces
Biosensors have become integrated into our lives. Current technology requires biosensors not only to have high sensitivity but also to have high specificity for one target, while repelling all other molecules and materials in the biological medium. These

Highly Stretchable, Adhesive, Biocompatible, and Antibacterial Hydrogel Dressings for Wound Healing

open access: yesAdvanced Science, 2021
Treatment of wounds in special areas is challenging due to inevitable movements and difficult fixation. Common cotton gauze suffers from incomplete joint surface coverage, confinement of joint movement, lack of antibacterial function, and frequent ...

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy

open access: yesAdvanced Healthcare Materials, EarlyView.
Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

Molecular Transport within Polymer Brushes: A FRET View at Aqueous Interfaces

open access: yesMolecules, 2022
Molecular permeability through polymer brush chains is implicated in surface lubrication, wettability, and solute capture and release. Probing molecular transport through polymer brushes can reveal information on the polymer nanostructure, with a ...
