Butterfly wings inspire new research
A technique that enables replicas of biological structures, such as butterfly wings, to be made on a nanometric scale has been developed by a team of researchers from the State University of Pennsylvania and the Universidad Autónoma de Madrid in Spain.
A window that washes itself
Nanotechnology has now produced a coating for windows or solar panels that repels grime and dirt.
Imaging collagen with X-rays
Coherent X-ray diffraction patterns of collagen in soft tissues have been measured for the first time by Dr Felisa Berenguer (London Centre for Nanotechnology) with her colleagues [paper to publish in PNAS 2009].
2000 year old Greek athlete sheds light on corrosion
Biomineralization studies of a recently discovered 2,000-year-old bronze sculpture may help modern scientists understand how to prevent metal corrosion, discover the safest ways to permanently store nuclear waste, and understand other perplexing problems. [Lyons et al., Cryst. Growth Des., DOI: 10.1021/cg900402b].

Analysis of an ultra hard magnetic biomineral in chiton radular teeth
Recent analyses of the ultrastructural and mechanical properties of mineralized biological materials have demonstrated some common architectural features that can help explain their observed damage tolerance.

Replication of the 3D architecture of tissues
Biological tissues are ensembles of various types of cells and extracellular molecules. Functionality in tissues arises from their components (cells and extracellular molecules) as well as from the location of those components relative to each other. The organization of the constituents of a tissue is known as histoarchitecture.
Resorbable biomaterials as bone graft substitutes
An ageing population and the democratization of high-risk sports have led to a surge of bone-related diseases and bone fractures. As a result, the use of bone graft substitutes has dramatically increased in the last decade.

Self-assembling peptide nanotubes
Biological proteins and peptides have the intrinsic ability to self-assemble into elongated solid nanofibrils, which may give rise to amyloid diseases or inspire applications ranging from tissue engineering to nanoelectronics.
Protein-nanoparticle interactions
The key role of protein-nanoparticle interactions in nanomedicine and nanotoxicity has begun to emerge recently with the development of the idea of the nanoparticle-protein ‘corona’.
