Nanoscale article in Chemistry World: Biomimetic bricks inspired by mother of pearl

09 Apr 2013

Chinese chemists have developed a new nacre-like material which is stronger than natural nacre and most other composites.

Nacre, which is also known as mother of pearl, is a naturally occurring composite formed from calcium carbonate and biopolymers that create a brickwork structure. It is also nearly a thousand times stronger than any of its component parts and a major target for biomimetic synthesis.

Design of the brickwork structure is central to developing nacre-like materials with enhanced properties. Gaoquan Shi, and colleagues, at Tsinghua University, Beijing, began by making a hydrogel from graphene and a silk protein, called fibroin.

New method to target malaria: Nanoscale article in Chemistry World

22 Jan 2013

Malaria is a highly infectious and potentially fatal mosquito-borne disease. It affects millions of people each year; however, no effective vaccines exist. Now, scientists from Spain have discovered a new strategy to target the disease.

Plasmodium falciparum, the most deadly species of malaria parasite, infects red blood cells (RBCs) and changes their structure. The infected RBCs then bind to the walls of blood vessels in tissues, such as the brain and lungs, through a phenomenon known as sequestration. This allows the malaria parasites to replicate. Infected RBCs can also bind to non-infected RBCs, forming clumps known as rosettes, which narrows the blood vessels and can be fatal. The formation of rosettes is thought to be mediated by a protein called PfEMP1, which is expressed at the surface of infected RBCs. So, disrupting the activity of this protein could help prevent rosette formation and the onset of severe malaria.

Bactericides reach new depths: Nanoscale article in Chemistry World

07 Dec 2012

P. aeruginosa: (A) without treatment; treated with (B) bismuth nanoparticles; (C) x-rays; (D) x-rays and bismuth nanoparticles

Scientists in the US and China have come up with a low-risk treatment for bacterial infections in a deep wound.

Treating infections has long been a challenge for healthcare professionals, and infections caused by drug resistant bacteria have made this task even more difficult to manage. Recently, the genome of an MRSA (methicillin-resistant Staphylococcus aureus) outbreak in a hospital was sequenced to identify the source of infection, track its spread and avoid an outbreak.1 Such extreme measures of tracing infection need an equally tough bactericide. X-ray irradiation is known to have bactericidal properties; however, the high doses needed and the associated risks have restricted its use in vivo.

Oil loving membranes for oil spill clean-ups: Nanoscale article in Chemistry World

13 Nov 2012

Researchers in China have made a new type of membrane that can separate oil from water and could potentially be used in oil spills, such as the one in the Gulf of Mexico. The membrane works by interacting differently with the substances as it is both superhydrophobic and superoleophilic, so that it repels water but attracts oil. This means that the oil is absorbed through the membrane, but the water can’t penetrate.

Oil and water separation using the membrane. The water and oil were dyed by methyl blue and oil red, respectively

The membrane is made from a polymerised fluorinated polybenzoxazine (F-PBZ) layer on top of cellulose acetate nanofibres. The scientists used an electrospinning technique (in which a viscous liquid is passed through a conducting needle to form a thread) to create a porous structure that makes the membrane even better at absorbing the oil.
