Artificial Nanopores Take Analyte Pulse
(31 Jul 2007)
Reliable nanopores by two-step etching
Resistive pulse sensing represents a very attractive method for identifying and quantifying biomedical species such as drugs, DNA, proteins, and viruses in solution. This method involves measuring changes in the ionic current across a membrane ...

Stretching DNA to the Limit
(25 Apr 2007)
DNA damage in a new light
It has long been known that UV light can damage DNA, reducing its ability to replicate and interact with proteins, and often resulting in the development of skin cancers. However, not much is known about how the elasticity of DNA strands is altered ...

Plug and play bone repair
(07 Mar 2007)
A modified ink-jet printer can be used to directly print layer upon layer of artificial bone for quick-fix grafts used in reconstructive surgery
Bone takes a long time to grow and repair, so treating serious damage or carrying out reconstructive procedures can be a slow and painstaking process. Jake Barralet of the Faculty of Dentistry, at McGill University and Uwe Gbureck, Department for ...

Plastic biochip speeds up protein detection
(10 Oct 2006)
Using fluorescent polymers to quickly detect attomoles of protein
A new, fast, and inexpensive way to test for medically important molecules, such the blood clot protein thrombin and faulty proteins present in Alzheimer's disease, could emerge from research published in the journal Advanced Materials. Mario ...

New and improved right to the last drop
(28 Jul 2006)
Trapping enzymes in silica beads
Biomolecules have become almost ubiquitous in laundry and personal care products. Biological washing powders usually contain enzymes to help digest stains while the latest shampoos and conditioners often use proteins to add shine and thickness to ...

Cancer Drug from Sea Sponges?
(09 Sep 2004)
Marine organisms are a real treasure trove for new drug candidates. Take Dictyostatin, for example: a cytotoxic compound obtained in milligram scale from a sea sponge, which could have what it takes to treat cancer. The exact structure of this ...
