Single‐Particle Characterization Reveals Heterogeneous Extracellular Vesicle Fusion with Liposomes

Small Methods, EarlyView.
This study used five orthogonal single‐particle techniques to compare how common mechanical methods fuse extracellular vesicles with liposomes. By quantifying fused‐particle yield, purity, and vesicle integrity, we found that freeze‐thaw and sonication generated the highest fusion but that all methods introduced membrane perturbation or damage.

Spectral Unmixing With Perturbed Endmembers

IEEE Transactions on Geoscience and Remote Sensing, 2017
We consider the problem of supervised spectral unmixing with a fully-perturbed linear mixture model where the given endmembers, as well as the observations of the spectral image, are subject to perturbation due to noise, error, mismatch, etc. We calculate the Fisher information matrix and the Cramer-Rao lower bound associated with the estimation of the

Immune cells composition in the skin and subcutaneous adipose tissue of patients with systemic sclerosis

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and objectives Systemic sclerosis (SSc) is a rare, chronic autoimmune disease characterized by fibrosis of the skin and/or internal organs. Emerging evidence suggests that subcutaneous adipose tissue may contribute to systemic inflammation and fibrosis in SSc.

Single‐molecule validation and optimised protocols for the use of secondary nanobodies in multiplexed immunoassays

Journal of Microscopy, EarlyView.
Abstract Recently developed secondary nanobodies or single‐domain antibodies present a powerful tool for immunodetection. Unlike traditional antibodies, their monovalence enables pre‐association with primary antibodies prior to sample staining, presenting a straightforward affinity‐based antibody labelling solution.

UnMix-NeRF: Spectral Unmixing Meets Neural Radiance Fields

Neural Radiance Field (NeRF)-based segmentation methods focus on object semantics and rely solely on RGB data, lacking intrinsic material properties. This limitation restricts accurate material perception, which is crucial for robotics, augmented reality, simulation, and other applications.

Fluorescent proteins: A journey from the cell to extreme environments in material science

Photochemistry and Photobiology, EarlyView.
Applications of proteins and microorganisms as tools or effectors in material science. Abstract This review presents the progression from the use of fluorescent proteins (FPs) and chromoproteins as bioimaging labels and sensors to the strategic engineering of their properties for robust functionality in synthetic and non‐biological environments ...

Hyperspectral Unmixing With Multi-Scale Convolution Attention Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Hyperspectral unmixing is to decompose the mixed pixel into the spectral signatures (endmembers) with their corresponding abundances. However, the ignorance of endmember variability in hyperspectral unmixing results in low performance.
