Direct measurement of protein dipoles reveals the mechanism for like-charge adsorption on silica

Nature Communications
Negatively charged particles are expected to adsorb with difficulty onto negatively charged surfaces. However, some proteins do. In this work, we use ferritin as a model protein particle to study its adsorption onto a negatively charged silica surface ...

Lateral Piezoelectricity of Alzheimer's Aβ Aggregates

Advanced Science
Alzheimer's disease (AD) is the most frequent neurodegenerative disorder in the elderly aged over 65. The extracellular accumulation of beta‐amyloid (Aβ) aggregates in the brain is considered as the major event worsening the AD symptoms, but its ...

Adaptive filtering on KPFM data: a deep neural network approach

Machine Learning: Science and Technology
Kelvin probe force microscopy (KPFM) measurements often exhibit widely varying signal-to-noise ratios (SNR) because of non-ideal acquisition conditions, especially in time-sensitive experiments.
