Photothermal–Immunomodulatory Hydrogel Reinforced by Ti3C2/ZnAl‐LDH Nanoplatform for Eradicating MRSA and Promoting Diabetic Wound Healing

open access: yesAdvanced Science, EarlyView.
A NETs‐inspired Ti3C2/LDH hydrogel integrates trapping, ROS boosting, and M2‐immunomodulation for MRSA‐infected wound repair. ABSTRACT MRSA infections give rise to chronic cutaneous and advance into profound tissue invasions, including osteomyelitis and sepsis—conditions for which existing clinical interventions offer only limited efficacy. The utility

A Mini‐Spidroin Forms High‐Performance Artificial Spider Silk via Edge‐Cysteine–Locked β‐Sheet Assembly

open access: yesAdvanced Science, EarlyView.
Cysteine‐engineered mini‐spidroins (∼33 kDa) undergo phosphate‐induced liquid–liquid phase separation (LLPS), where disulfide bonds lock partially aligned polyA segments. Subsequent microfluidic spinning promotes directional β‐sheet crystallization, producing fibers with 531 MPa strength and 182 MJ/m3 toughness.

Visualizing and Quantifying Impact with Mechanochromic Sensing Paints Based on Self‐Assembled Polydiacetylene‐Silk Core‐Shell Vesicles

open access: yesAdvanced Science, EarlyView.
Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

NIR Light‐Driven Photocatalytic Antibacterial Hydrogels for Synergistic MRSA Biofilm Eradication and Wound Regeneration

open access: yesAdvanced Science, EarlyView.
The nanohybrid hydrogel (Fe‐BOS@C/H Gel) is composed of Fe‐Bi2O2‐XS (Fe‐BOS) photocatalysts and CS‐ADH/OHA (C/H) hydrogel. Fe‐BOS photocatalysts achieve near‐infrared (NIR) light‐driven antibacterial photocatalytic/mild photothermal therapy (APCT/MPTT), effectively eliminating methicillin‐resistant Staphylococcus aureus (MRSA) biofilms. The degradation

Substituent‐Based Modulation of Self‐Assembly and Immunogenicity of Amphipathic Peptides

open access: yesAdvanced Science, EarlyView.
This study systematically investigates how positional and subtle changes, such as substituents on the phenyl ring attached to short amphipathic peptides, influence their self‐assembly, fibril morphology, and immunogenic responses. ABSTRACT Self‐assembled peptide‐based biomaterials provide versatile platforms for biomedical uses, featuring customizable ...

Light sheet fluorescence microscopy

Nature Reviews Methods Primers, 2021
Light sheet fluorescence microscopy (LSFM) uses a thin sheet of light to excite only fluorophores within the focal volume. Light sheet microscopes (LSMs) have a true optical sectioning capability and, hence, provide axial resolution, restrict photobleaching and phototoxicity to a fraction of the sample and use cameras to record tens to thousands of ...

Practical considerations for quantitative light sheet fluorescence microscopy

Nature Methods, 2022
Fluorescence microscopy has evolved from a purely observational tool to a platform for quantitative, hypothesis-driven research. As such, the demand for faster and less phototoxic imaging modalities has spurred a rapid growth in light sheet fluorescence microscopy (LSFM).

Fast Fluorescence Microscopy with Light Sheets

The Biological Bulletin, 2016
In light sheet microscopy, optical sectioning by selective fluorescence excitation with a sheet of light is combined with fast full-frame acquisition. This illumination scheme provides minimal photobleaching and phototoxicity. Complemented with remote focusing and multi-view acquisition, light sheet microscopy is the method of choice for acquisition of

Digital Scanned Laser Light Sheet Fluorescence Microscopy

Cold Spring Harbor Protocols, 2010
INTRODUCTIONModern applications in the life sciences are frequently based on in vivo imaging of biological specimens, a domain for which light microscopy approaches are typically best suited. Often, quantitative information must be obtained from large multicellular organisms on the cellular or even subcellular level and with a good temporal resolution.

Light-sheet fluorescence microscopy with metalens

ODS 2020: Industrial Optical Devices and Systems, 2020
We propose a Light-sheet fluorescent microscopy (LSFM) system with a flat metalens, which is used to replace the bulky illuminating components. The metalens is a diffractive optics elements (DOEs) composed of various gallium nitride (GaN) nanopillar for light-sheet generation, and it can be readily integrated in existing LSFM systems.
