Platinum nanoparticles shown to strongly enhance the efficacy of radiation therapy

nanowerk.com –

Cancer treatment typically involves chemotherapy, radiotherapy, or surgery, and – depending on the stage of the disease – often is unsuccessful. The most common drawback of all conventional treatments is that they are very imprecise due to a lack of selectivity between malignant and healthy cells. In contrast, nanotechnology offers a vision for a new approach to fighting tumors: the ability of nanoparticle-based techniques to locate cancer cells and destroy them with single-cell more...

Re-shaping bacterial inclusion bodies as improved nanomaterials for tissue engineering

nanowerk.com –

Cultured mammalian cells prefer growing on structured rather than on completely flat surfaces. In regenerative medicine, in which human cells must grow on artificial scaffolds to replace damaged tissue, appropriate biological signals, such as growth factors, but also mechanic stimuli should be provided at the nano and microscales for cell attachment and proliferation, mimicking the natural cell matrices in organic tissues. The straightforward fabrication of nanostructured surfaces as scaffolds more...

Bio-assembler uses magnetic levitation to assemble 3-D cell cultures

nanowerk.com –

Mass culture of cell lines has long been fundamental to the manufacture of viral vaccines and many products of biotechnology. More recently it also has become an essential tool in stem cell research and tissue engineering. Most conventional petri dish based cell culture techniques produce monolayers cell growth that is missing essential cellular functions that are present in living organisms; gene expression, signaling and morphology can be different and this compromises its clinical relevance. more...

Nanotechnology trap captures cancer cells in blood

nanowerk.com –

Metastasis is caused by marauding tumor cells that break off from the primary tumor site and ride in the bloodstream to set up colonies in other parts of the body. These breakaway cancer cells in the peripheral blood are known as circulating tumor cells (CTCs). Detecting and analyzing these cells can provide critical information for managing the spread of cancer and monitoring the effectiveness of therapies. Nanotechnology researchers have now developed a an efficient cell-capture platform more...

Remote-controlled nanocomposite for on-demand drug delivery inside the body

nanowerk.com –

Quite a number of serious medical conditions, such as cancer, diabetes and chronic pain, require medications that cannot be taken orally, but must be dosed intermittently, on an as-needed basis, and over a long period of time. By combining magnetism with nanotechnology, researchers have now created a small implantable device that encapsulates the drug in a specially engineered membrane, embedded with magnetic iron oxide nanoparticles. The application of an external, alternating magnetic field more...

Molecular capture with protein nanotechnology

nanowerk.com –

In many biomedical applications, protein nanotubes present several advantages over nano-spheres. The layer-by-layer (LbL) deposition technique for the preparation of protein nanotubes has attracted considerable attention because of their potential nanotechnology applications in enzymatic nanocatalysts, bioseparation nano-filters, and targeting nanocarriers. A drawback is that in template synthesis the extraction process often results in physical deformation of the nanotubes. Researchers in more...

Quantum dot based siRNA approach selectively inhibits brain cancer cells

nanowerk.com –

Oncogenes are genes that are associated with the development of cancer - when mutated or expressed at high levels, they can help turn a normal cell into a tumor cell. Promising new chemotherapeutic strategies have therefore focused on suppressing oncogenes. One such approach is based on RNA interference (RNAi), a technique wherein small double-stranded RNA molecules can sequence-specifically inhibit the expression of targeted oncogenes. The idea here is that with the help of small interfering more...

Nanotechnology Sensor Detects Living Bacteria at Ultralow Concentrations

nanowerk.com –

In their effort to develop a fast, sensitive, selective, inexpensive, and easy-to-use method for detecting and quantifying pathogenic bacterial cells, researchers in Spain have now demonstrated a carbon nanotube based potentiometric biosensor for selectively detecting one single colony-forming unit of the bacterium Salmonella Typhi in close to real time. The most important strength of this biosensor is that simple positive/negative tests can be carried out in real zero-tolerance conditions and more...

Regulating Nanotechnologies: Risk Management Models

joachimschummer.net –

'At the current stage, nanotechnologies affect many areas of law: occupational health and safety, environmental protection, consumer protection, medical law, privacy and civil liberties, intellectual property and patent law. Nonetheless, the analysis of the legal implications of nanotechnologies is just at the beginning. What is particularly needed is an overall view of the principles that can guide the legal approach. This special issue on Regulating Nanotechnologies aims to provide this kind more...
