Tiny Rare-Earth Fluoride Nanoparticles Activate Tumour Cell Growth via Electrical Polar Interactions

Nanoscale Research Letters, 2018
Localised extracellular interactions between nanoparticles and transmembrane signal receptors may well activate cancer cell growth. Herein, tiny LaF3 and PrF3 nanoparticles in DMEM+FBS suspensions stimulated tumour cell growth in three different human ...

Sensing the structural and conformational properties of single-stranded nucleic acids using electrometry and molecular simulations

Scientific Reports
Inferring the 3D structure and conformation of disordered biomolecules, e.g., single stranded nucleic acids (ssNAs), remains challenging due to their conformational heterogeneity in solution.

Structural dynamics of myosin 5 during processive motion revealed by interferometric scattering microscopy

eLife, 2015
Myosin 5a is a dual-headed molecular motor that transports cargo along actin filaments. By following the motion of individual heads with interferometric scattering microscopy at nm spatial and ms temporal precision we found that the detached head ...

Local unfolding of the HSP27 monomer regulates chaperone activity

Nature Communications, 2019
The small heat-shock protein HSP27 occurs predominantly in oligomeric forms, which makes its structural characterisation challenging. Here the authors employ CPMG and high-pressure NMR with native mass spectrometry and biophysical assays to show that the

Stick–slip behaviour on Au(111) with adsorption of copper and sulfate

Beilstein Journal of Nanotechnology, 2015
Several transitions in the friction coefficient with increasing load are found on Au(111) in sulfuric acid electrolyte containing Cu ions when a monolayer (or submonolayer) of Cu is adsorbed.
