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

Advanced 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

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

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

Advanced 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 ...

Wavelength-dependent feedback behavior in light-gated polymersome nanoreactors

Nature Communications
Biological systems integrate multiple feedback processes to regulate their adaptation to evolving stimuli with high specificity. Inspired by wavelength-selective feedback processes in visual signaling, we present a synthetic nanoreactor system capable of

Temperature- and Emission Wavelength-Dependent Time Responses of Strontium Aluminates

Crystals
In this paper, we study the temperature- and emission wavelength-dependent time responses of previously reported precursor-driven Eu2+- and Dy3+-doped strontium-aluminate phosphors to create unique luminescent anti-counterfeiting tags suitable for ...

Wavelength-Dependent Calcium Signaling Response to Photobiomodulation in Pancreatic Cells

Photonics
Diabetes mellitus is a metabolic disorder that is rapidly growing across the world. Our laboratory has recently demonstrated that photobiomodulation (PBM) can couple to its metabolic pathways by modulating calcium dynamics in islet cells, including α ...

Wavelength dependence of fused couplers

Electronics Letters, 1986
The transmission characteristics of fused couplers are evaluated as a function of the cross-sectional radius and the degree of fusion. The wavelength dependence of the coupling ratio is then examined with a view to minimising the wavelength dependence in wavelength-multiplexed optical networks.

Comparison of Full Wavefield Synthetics with Frequency-Dependent Traveltimes Calculated Using Wavelength-Dependent Velocity Smoothing

, 2017
Ray theory-based traveltime calculation that assumes infinitely high frequency wave propagation is likely to be invalid in the near-surface (upper tens of meters) due to the relatively large seismic wavelength compared with the total travel path lengths ...
