Scientists draw lessons for nanotechnology from wide range of biological machinery

A recent review article delineates engineering principles that may prove valuable for engineering complex nanosystems that can be discerned from the molecular mechanisms by which such biological molecular motors operate and are controlled.

Nanotechnology delivers safer MRI contrast agent to image clots

A novel toroidal-shaped nanoparticle provides a nanotech way to image blood clots without using magnetic resonance imaging contrast agents that are toxic to some patients.

Nanotechnology creates structures that mimic proteins

A major advance in mimicking protein function has been made by scientists working with peptoids.

Roundup and removal of cancer cells using nanotechnology

A nanotech method to capture cancer cells and remove them from the body might be useful for combating ovarian cancer, in particular.

Nanotechnology may be able to deliver drugs across the blood-brain barrier

Researchers expect protein-conjugated quantum rods to be able to transport multiple agents across the blood-brain barrier so that they could function synergistically.

Nanotechnology therapies for cancer progress, block metastasis

In experiments in mice, chemotherapy drugs encapsulated in nanoparticles targeted to the blood vessels that supply nutrients to tumor cells prevented the usually fatal spread of the cancer to additional sites.

Nanotechnology may allow hip implants to sense growth of new bone

The nanotech-prepared titanium surface serves as a sensor to detect bone formation.

Artificial DNA base pairs for nanotechnology building blocks

An ‘artificial DNA’ in which the two natural DNA base pairs have been replaced by two non-natural base pairs may provide useful new nanotech building blocks.

Nanotechnology mimics virus sizes and shapes for more efficient gene therapy

A nanotech replacement for virus vectors offers a safer way to introduce DNA into cells for gene therapy.

Formulating an anticancer drug using nanotechnology eliminates toxic neurological side-effects

A nanotech formulation may have saved one of the most promising broad-spectrum antiangiogenesis cancer therapies from being side-tracked due to neurotoxic side effects.
