Silver Nanoparticles as Optical Sensors [PDF]

open access: yes, 2010
The use of silver nanoparticles (AgNPs) as analytical and bioanalytical sensors is receiving significant attention. This relevance arises from its unusual optical, electronic, and chemical properties (Schultz et al., 2000; Taton et al., 2000; Yguerabide & Yguerabide, 1998).

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

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 ...

Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

open access: yesAdvanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Programming Nanoscale Reaction Environments via Peptide Localization for Gold Nanoparticle Growth in Liposomal Nanoreactors

open access: yesAdvanced Functional Materials, EarlyView.
The liposome nanoreactor method enables uniform metal nanoparticle synthesis using the interior as a reaction environment. We demonstrate that peptide sequences and lipid compositions act as a functional molecular switch to control reaction environments in liposome nanoreactors.

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,
