Multiplexed redox gating measurements with a microelectrospotter. Towards electrochemical readout of molecularly imprinted polymer microarrays

Electrochemistry Communications, 2020
Here we show that the microelectrospotting approach that we proposed earlier (M. Bosserdt et al., Biosens. Bioelectron., 73 (2015) 123–129) to generate molecularly imprinted polymer-based protein microarrays by electrosynthesis can also offer a means for

Partial Phase‐Separation in the Initial Growth Stage of Exsolution‐Active SrTi0.95‐xNi0.05NbxO3‐δ Thin Films

Advanced Science, EarlyView.
Phase separation emerges during the initial growth of heavily Ni‐ and Ni,Nb‐co‐doped STO thin films, leading to preferential accumulation of Ni and embedded NiOx nanoinclusions in thicker films. Nb co‐doping partially suppresses the ordering of these embedded structures, comprising about 20% of all Ni ions.

Protease‐Triggered Chromogenic Release From Peptide‐Modified Calcium Carbonate Microspheres Enables Colorimetric Detection of Porphyromonas gingivalis Activity

Advanced Science, EarlyView.
We report a chromogenic release‐based assay system with protease‐cleavage peptide‐modified calcium carbonate microspheres for colorimetric detection of Porphyromonas (P.) gingivalis activity. In response to Arg‐specific gingipain secreted by P. gingivalis, the supernatant becomes colored, enabling colorimetric analysis and providing the monitoring of ...

Probing the Energy Landscape of α‐Synuclein Amyloid Fibril Formation by Systematic K‐to‐Q Mutagenesis

Advanced Science, EarlyView.
We use lysine‐to‐glutamine mutations to study the effect of electrostatics on the kinetics and thermodynamics of alpha‐synuclein amyloid fibril formation. We find that mutational effects map on their structural context within fibrils and identify residues that modulate the energy landscape of alpha‐synuclein self‐assembly. Our work outlines a scalable,

Synergistic Mechano‐Fluidic Self‐Fusion of Poly(Vinyl Alcohol)‐Modified Liquid‐Metal Particles for Post‐Treatment‐Free Soft Electronics

Advanced Science, EarlyView.
Poly(vinyl alcohol)‐modified liquid‐metal particles form conductive networks through spray‐induced self‐fusion without additional post‐treatment. Spray impact initiates oxide‐shell rupture and electrical contact, while subsequent Marangoni flow and capillary forces promote particle redistribution, neck growth, and network consolidation. This sequential

Quantifying Structure‐Dependent Rigidity of 3D DNA Origami Boxes

Advanced Intelligent Systems, EarlyView.
We investigate the mechanical stability of a hollow 3D DNA origami box during assembly using liquid AFM imaging and finite element simulations. As structural completeness increases from flat sheets through intermediate assemblies to a closed box, rigidity improves.

Tackling cancer stemness with nanotechnology in the era of precision medicine

BMEMat, EarlyView.
Precise customization of nanoparticles (NPs) enables active targeting of cancer stem cells (CSCs), thereby improving drug delivery and therapeutic efficacy. NP‐based probing enhances CSC detection through imaging and liquid biopsy, whereas diverse therapeutic payloads improve therapeutic outcomes.
