Small-molecule uptake in membrane-free peptide/nucleotide protocells
TL;DR: The results suggest that understanding the mechanisms of molecular uptake into coacervate droplets could provide an important step towards the rational design of molecularly crowded microscale dispersions that display complex fluid behavior, compartment-mediated functionality and primitive aspects of synthetic cellularity.

Real-time nanofabrication with high-speed atomic force microscopy.
JA Vicary,Mervyn J Miles +1 more
TL;DR: The application of a previously described high-speed atomic force microscope for nanofabrication concerns the modification of a silicon surface by locally oxidizing the region in the vicinity of the AFM tip.

Correlation of in situ mechanosensitive responses of the Moraxella catarrhalis adhesin UspA1 with fibronectin and receptor CEACAM1 binding
Christopher R. Agnew,Elena Borodina,Nathan R. Zaccai,Rebecca Conners,Nicholas M. Burton,JA Vicary,David K. Cole,Massimo Antognozzi,Mumtaz Virji,R L Brady +9 more
TL;DR: This study investigates the physical deformability of the UspA1 adhesin protein from Moraxella catarrhalis, a causative agent of middle-ear infections in humans and provides a rare direct demonstration of protein conformational change at the cell surface.

Pushing the boundaries of local oxidation nanolithography: Short timescales and high speeds
JA Vicary,Mervyn J Miles +1 more
TL;DR: It is shown that the local oxidation of hydrogen-passivated silicon surfaces by intermittent-contact mode atomic force microscopy can be applied on timescales as low as 500 ns to create single oxide nanostructures with dimensions of 0.6 x 15 nm(2).

Methods for imaging DNA in liquid with lateral molecular-force microscopy.
TL;DR: It is shown that the recently developed scattered evanescent wave (SEW) detection system, combined with custom-designed vertically oriented cantilevers (VOCs), can reliably produce true non-contact images in liquid of DNA molecules.
