Antibody replacements just a 'click' away

Chemists at the California Institute of Technology (Caltech) and The Scripps Research Institute (SRI) have developed an innovative technique to create cheap but highly stable chemicals that have the potential to take the place of the antibodies used in many standard medical diagnostic tests.

Accoustic tweezers to place nano-objects

Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be small enough to place on a chip, according to Penn State engineers.

Nanoflares light up molecules in live cells

By combining a gold nanoparticle with a unique family of nucleic acids, researchers at Northwestern University have created a new type of intracellular reporting system that with a flash of light reveals the presence and quantity of a wide variety of biologically important molecules.

Nanotubes destroy kidney tumors

By injecting multiwalled carbon nanotubes into tumors and heating them with a quick, 30-second zap of a laser, a multi-institutional team of researchers has developed a new type of therapy that effectively kills kidney tumors in nearly 80% of treated mice.

Nanoparticles detect and profile cancer cells rapidly

Using a new type of paramagnetic nanoparticle and a nuclear magnetic resonance (NMR) system built into a microfluidic device, a team of investigators at the Massachusetts General Hospital and Harvard Medical School has created an assay system capable of detecting as few as two cancer cells in 1 microliter of biological fluid. In addition, the new assay requires little sample processing and produces results in less than 15 minutes.

New cancer drug delivery system Is effective and reversible

For cancer drug developers, finding an agent that kills tumor cells is only part of the equation. The drug also must spare healthy cells, and ideally its effects will be reversible to cut short any potentially dangerous side effects. Investigators from the University of Illinois at Urbana-Champaign report that they have assembled a new cancer drug delivery system that, in cell culture, achieves all of the above.

Intercepting neuronal transmissions with a genetically encoded fluorescent sensor

The nervous system's circuitry is linked together via intercellular junctions known as synapses, and signal transmission across these connections depends on neurotransmitters?specific chemicals that directly deliver excitatory or inhibitory signals from one neuron to another. Scientists are now able to monitor receptor activity in living cells with unprecedented precision.
