FRAP: A Powerful Method to Evaluate Membrane Fluidity in Caenorhabditis elegans

Bio-Protocol, 2018
FRAP (Fluorescence Recovery After Photobleaching) is probably the most direct method to investigate the dynamics of molecules in living cells. Here, we describe FRAP to quantify membrane fluidity in C. elegans.

Studying Protein Aggregation in the Context of Liquid-liquid Phase Separation Using Fluorescence and Atomic Force Microscopy, Fluorescence and Turbidity Assays, and FRAP

Bio-Protocol, 2020
Liquid-liquid phase separation (LLPS) underlies the physiological assembly of many membrane-less organelles throughout the cell. However, dysregulation of LLPS may mediate the formation of pathological aggregates associated with neurodegenerative ...

pH‐Tunable Material Properties of Glycine‐Rich Condensates from Tick Bioadhesive

Advanced Functional Materials, EarlyView.
This work studies the influence of pH on the phase separation behavior of a disordered glycine‐rich protein found in tick bioadhesive. The results show profound impact on the propensity of coacervation, condensate microstructure and viscosity, amphiphilicity of the peptides, and effective encapsulation of therapeutic molecules.

Upconversion Nanoparticles Embedded Photonic Contact Lens for Transepithelial Corneal Crosslinking Using Hyaluronate – Riboflavin Conjugate

Advanced Functional Materials, EarlyView.
A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...
