Luminescent upconversion nanocrystals can detect cancer cells

Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These materials could be used as biomarkers for luminescent labeling of cancerous cells. Opaque tissues can be turned into glassy, transparent substances by using these biomarkers which rely on near-infrared excitation.

CFN scientists develop 2-component polymer scaffolds for controlled 3-D cell culture

At Karlsruhe Institute of Technology (KIT), researchers of the DFG Center for Functional Nanostructures (CFN) succeeded in specifically cultivating cells on three-dimensional structures. The fascinating thing is that the cells are offered small "holds" in the micrometer range on the scaffold, to which they can adhere. Adhesion is possible to these holds only, not to the remaining structure.

New ‘nanotech’ weapon against drug-resistant superbugs

Scientists at the Institute of Bioengineering and Nanotechnology (IBN) and IBM Research – Almaden have developed the first biodegradable polymer nanoparticles to combat drug-resistant superbugs, such as Methicillin-Resistant Staphylococcus aureus (MRSA). These nanoparticles can selectively kill the bacteria without destroying healthy red blood cells, and being biodegradable, have great potential to treat infectious diseases in the body. This was reported today in the leading scientific journal, Nature Chemistry [(2011) DOI: 10.1038/nchem.1012].

Combined diagnosis and treatment of tumors: photothermically activated ultrasound contrast agent

Diagnosis and treatment form the basis of modern medicine. Traditionally, they are two separate steps; however, it doesn’t have to be that way. The term “theranostic” refers to the combination of a diagnostic test with a specific treatment based on the result of the test. This integrated approach should be particularly helpful in providing more targeted treatment for cancer patients.

Simpler method of making water-soluble short protein chains with spiral structures

Researchers have developed a simple method of making short protein chains with spiral structures that can also dissolve in water, two desirable traits not often found together. Such structures could have applications as building blocks for self-assembling nanostructures and as agents for drug and gene delivery.

Findings could speed use of RNA nanotechnology for treating disease

Scientists are reporting an advance in overcoming a major barrier to the use of the genetic material RNA in nanotechnology - the field that involves building machines thousands of times smaller than the width of a human hair and now is dominated by its cousin, DNA. Their findings, which could speed the use of RNA nanotechnology for treating disease, appear in the monthly journal ACS Nano.

Mechanism for binding oxygen to metalloporphyrins seen on a molecular level

The mechanism for binding oxygen to metalloporphyrins is a vital process for oxygen-breathing organisms. Understanding how small gas molecules are chemically bound to the metal complex is also important in catalysis or the implementation of chemical sensors. When investigating these binding mechanisms, scientists use porphyrin rings with a central cobalt or iron atom. They coat a copper or silver support surface with these substances.

Two-dimensional crystals from DNA origami tiles

DNA is more than just a carrier for our genetic information; DNA is also an outstanding nanoscale building material, as researchers led by Ned Seeman discovered thirty years ago. Seeman and his colleagues at the New York University (USA) have now used cross-shaped DNA tiles to produce an amazingly large grid structure that resembles woven fabric. As the researchers report in the journal Angewandte Chemie, these two-dimensional crystals attain dimensions of about 2×3 micrometers.
