Diatoms, the most common type of algae, are one of the most prevalent organisms in the world. They live in wet ambient environments such as oceans, lakes and rivers and are easily recognizable because of their unique structure. Diatoms are surrounded by a silica cell wall called a frustule. The...
By taking advantage of the electron pathway through the heme group in cytochrome c (CytoC) electrochemists
have built sensors based upon CytoC immobilized onto metal electrodes. Previous studies have shown that the
electron transfer rate through the protein is a function of the position of this heme group with respect...
Previous studies have reported that the metastable vaterite phase of calcium carbonate can be stabilized in solution by acidic additives. Here we demonstrate that vaterite can also be stabilized directly at surfaces by engineered peptides. Our data show that the mineralisation occurs in a 'self-templating' process where calcium ions restructure...

The clotting protein von Willebrand factor (VWF) binds to platelet receptor glycoprotein Ibα (GPIbα) when VWF is activated by chemicals, high shear stress, or immobilization onto surfaces. Activation of VWF by surface immobilization is an important problem in the failure of cardiovascular implants, but is poorly understood. Here, the authors...

Biophysical studies of the interaction of peptides with model membranes provide a simple yet effective approach to understand the transport of peptides and peptide based drug carriers across the cell membrane. Herein, the authors discuss the use of self-assembled monolayers fabricated from the full membrane-spanning thiol (FMST) 3-((14-((40-((5-methyl-1-phenyl-35-(phytanyl)oxy- 6,9,12,15,18,21,24,27,30,33,37-undecaoxa-2,3-dithiahenpentacontan-51-yl)oxy)-[1,10-biphenyl]-4- yl)oxy)tetradecyl)oxy)-2-(phytanyl)oxy...
Dispersing hydrophilic nanofillers in highly hydrophobic polymer matrices is widely used to tune the mechanical properties of composite material systems. The ability to control the dispersion of fillers is closely related to the mechanical tunability of such composites. In this work, we investigate the physical–chemical underpinnings of how simple end-group...
