Recent Advances in Fluorescent Nanoparticles for Stimulated Emission Depletion Imaging

Biosensors
Stimulated emission depletion (STED) microscopy, as a popular super-resolution imaging technique, has been widely used in bio-structure analysis and resolving the dynamics of biological processes beyond the diffraction limit.

Suppression of quantum noises in coherent atom lithography through squeezing

, 2017
The Abbe's diffraction limit restricts the resolution of an optical imaging and lithography system. Coherent Rabi oscillation is shown to be able to overcome the diffraction limit in both optical and atom lithography.

Neurotrophic extracellular matrix proteins promote neuronal and iPSC astrocyte progenitor cell‐ and nano‐scale process extension for neural repair applications

Journal of Anatomy, Volume 246, Issue 4, Page 585-601, April 2025.
The extracellular matrix plays a critical role in modulating cell behaviour in the central nervous system influencing neural cell morphology and growth. However, a better understanding of the impact of individual matrix proteins on both neurons and astrocytes is critical for advancing the development of matrix‐based neural repair strategies.

When NCX switches sides: Experimental and computational insights into Ca2+ regulation in the heart

The Journal of Physiology, EarlyView.
Abstract figure legend Due to its presence inside the dyadic cleft, Na+/Ca2+ exchanger (NCX) builds a functional unit together with L‐type calcium channels and ryanodine receptors in the dyadic cleft. NCX acts bidirectionally (forward and reverse mode) dependent on extracellular calcium ([Ca2+]o) and sodium ([Na+]o) concentrations and the membrane ...

Vortex fibers for STED microscopy

APL Photonics, 2019
Super-resolution imaging using the principles of stimulated emission depletion (STED) microscopy requires collinear excitation of a sample with a Gaussian-shaped excitation beam and a donut-shaped depletion beam whose spin (polarization) and orbital ...

SARS‐CoV‐2 targets mitochondria, exacerbating COVID‐19 pneumonia

The Journal of Physiology, EarlyView.
Abstract figure legend Following entry into airway epithelial cells (AECs), SARS‐CoV‐2 releases its single‐stranded RNA into the cytoplasm, where it is translated into viral proteins. Several of these viral proteins localize to mitochondria and interact with key mitochondrial components.

Exploiting the tunability of stimulated emission depletion microscopy for super-resolution imaging of nuclear structures

Nature Communications, 2018
A known limitation of super-resolution STED microscopy is the need of high laser power which can cause photobleaching and phototoxicity. Here the authors further optimize this method and show that modulating STED intensity during acquisition results in ...

Developmental Profiling of Structural and Functional Maturation in Mouse Corpus Callosum

Glia, Volume 74, Issue 6, June 2026.
Progressive myelin development in mouse corpus callosum is accompanied by gradual decrease in oligodendrocyte precursor cell density and increase in oligodendrocyte density. Pro‐Capase‐3 is transiently upregulated in oligodendrocyte during postnatal development.

Protected STED and multicolour multilevel STED nanoscopy.

, 2016
The diffraction barrier of focused light has been overcome by modern superresolution fluorescence microscopy techniques. These methods harness transitions between signaling and non-signaling states of the marker molecules to make them discernible at length scales of few tens of nanometers. Although superresolution methods like STED (STimulated Emission

Lipid Nanoparticles for the Delivery of CRISPR/Cas9 Machinery to Enable Site‐Specific Integration of CFTR and Mutation‐Agnostic Disease Rescue

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
Lipid nanoparticles (LNPs) are optimized to co‐deliver Cas9‐encoding messenger RNA (mRNA), a single guide RNA (sgRNA) targeting the endogenous cystic fibrosis transmembrane conductance regulator (CFTR) gene, and homologous linear double‐stranded donor DNA (ldsDNA) templates encoding CFTR.
