An improved method for coating gold nanorods

Researchers have fine-tuned a technique for coating gold nanorods with silica shells, allowing engineers to create large quantities of the nanorods and giving them more control over the thickness of the shell. Gold nanorods ...

Engineers efficiently 'mix' light at the nanoscale

The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but the fundamentals ...

New nanodevice to improve cancer treatment monitoring

In less than a minute, a miniature device developed at the University of Montreal can measure a patient's blood for methotrexate, a commonly used but potentially toxic cancer drug. Just as accurate and ten times less expensive ...

Nanostructures filter light to order

Arrays of nanoscale pillars made to reflect light of a selected color could find application as optical filters in digital cameras.
