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

open access: yesAdvanced 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

Cellular interactions and design principles of glyco-gold nanoparticles for drug delivery applications

open access: yes, 2023
An escalating tendency prevails to manipulate gold-based nanoparticles decorated on their surfaces with different types of carbohydrates or glycopolymers for the development of versatile nanoplatforms—the so-called glyco-gold nanoparticles (GAuNPs) here ...

The Therapeutic Effect of Acoustic Cavitation on Breast Carcinoma Tumor Model in BALB/c Mice in the Presence of Gold Nanoparticles

open access: yesمجله دانشکده پزشکی اصفهان, 2019
Background: Acoustic cavitation, which occurs at high intensities of ultrasound waves, can be fatal for tumor cells. On the other hand, the existence of nanoparticles in a liquid decreases the acoustic cavitation onset threshold.

Electrostatic Superlattices Beyond 1:1 Stoichiometry

open access: yesAdvanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

open access: yesAdvanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...
