Mapping Protein–Protein Interactions of the Resistance-Related Bacterial Zeta Toxin–Epsilon Antitoxin Complex (ε2ζ2) with High Affinity Peptide Ligands Using Fluorescence Polarization

Toxins, 2016
Toxin–antitoxin systems constitute a native survival strategy of pathogenic bacteria and thus are potential targets of antibiotic drugs. Here, we target the Zeta–Epsilon toxin–antitoxin system, which is responsible for the stable maintenance of certain ...

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

Advanced 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,

Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

Advanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

Lipid-free apolipoproteins A-I and A-II promote remodeling of reconstituted high density lipoproteins and alter their reactivity with lecithin:cholesterol acyltransferase

Journal of Lipid Research, 1999
We examined the effect of lipid-free apolipoprotein A-I (apoA-I) and apoA-II on the structure of reconstituted high density lipoproteins (rHDL) and on their reactivity as substrates for lecithin:cholesterol acyltransferase (LCAT). First, homogeneous rHDL

Donor‐Engineered Chiral Indium–Salen Complexes for Tunable Circularly Polarized Luminescence

Advanced Functional Materials, EarlyView.
Chiral indium–salen complexes bearing electronically and structurally diverse donor substituents are presented as modular main‐group luminophores exhibiting tunable blue‐to‐green circularly polarized luminescence. Donor engineering systematically controls frontier‐orbital distribution, intraligand charge transfer, and excited‐state relaxation ...

Programmable Soft Actuator with Multi‐Responsiveness Based on Conductive MOF‐Liquid Crystal Polymer Composite

Advanced Functional Materials, EarlyView.
A sequential dual‐alignment strategy independently programs the orientation of conductive metal‐organic framework (c‐MOF) microrods and liquid crystals within a composite film. This approach creates an asymmetric bilayer structure that enables precise, multi‐responsive actuation.

Demo 24-04 Microwave Polarization

, 2001
This demonstration illustrates one mechanism for the polarization of electromagnetic waves, using the apparatus as shown in Figure 1. The result is counterintuitive in that the waves that pass through the polarizer are polarized perpendicular to the ...

Thermoresponsive Liquid Crystalline Polymer Coatings Programmed by Field‐Induced Topological Defects for Tunable Optical and Topographical Responses

Advanced Functional Materials, EarlyView.
Resonant standing waves generate large‐area lattices of liquid‐crystal topological defects that are permanently encoded into polymer coatings by photopolymerization. The preserved director architecture produces thermally reconfigurable surface topographies while maintaining programmable optical functionality, demonstrating a scalable strategy for ...

Demo 24-06 Polarization by Double Reflection

, 2001
Polarization of light is obtained by using two reflections from dielectric plates, as in Figure 1. This demonstration illustrates the effect of double reflection on the polarization of an initially unpolarized light beam.
