Nanovip All things Nanotechnology – Nano Is The Futiure

CHENNAI: The Tamil Nadu Veterinary and Animal Sciences University plans to set up a nanotechnology centre on the university’s Madhavaram campus this year. University vice-chancellor Dr R Prabakaran said, “We have been engaged in research in the field in bits and pieces in different departments now. All the research will be brought under a single umbrella at the centre.” He ... Read More »

PHILADELPHIA — Many recent advances in microtechnology and nanotechnology depend on microscopic spherical particles self-assembling into large-scale aggregates to form a relatively limited range of crystalline structures.  Directed assembly is a new branch of this field, where scientists figure out how to make particles assemble to form a broad range of structures at given locations. Current techniques for directed assembly typically ... Read More »

Spanish and German researchers have made a new instrumental development that solves a key materials science and nanotechnology question: how to chemically identify materials at the nanometre scale. One of modern chemistry and materials science’s main goals is to achieve the non-invasive chemical mapping of materials with nanometre-scale resolution. Although a variety of high-resolution imaging techniques currently exist, such as ... Read More »

  Introduction Many biological structures and systems have nanoscale features which affect their properties and behaviour. As our understanding of synthetic nanotechnology increases, we are beginning to see more and more clearly how these relationships between size, shape, and functionality work in biological systems. As we understand more and more about biological processes, it seems likely that some of the ... Read More »

Introduction Cancer is one of the biggest killers in the world, causing around 13% of deaths in 2007. Whilst there have been considerable improvements in the way cancer is treated, there is no definitive cure. When cancers are detected at an early stage, current treatments can be very effective, and the survival rate from these cases is very encouraging. The ... Read More »

Nano-FTIR can be applied for the chemical identification of nanoscale sample contaminations. This figure shows AFM images of a PMMA film on a Si surface. While the AFM phase contrast indicates the presence of a 100 nm size contamination, the determination of its chemical identity remains elusive from these images. Using nano-FTIR to record a local infrared spectrum in the ... Read More »

  Xiaowei Liu examines cells to test whether DNA nanostructures could reside comfortably within the appropriate compartment of the cells and be stable for several hours – long enough to set in motion an immune cascade Scientists at the Biodesign Institute at Arizona State University have turned to DNA nanotechnology to make an entirely new class of synthetic vaccines.
