Vaccine Delivery Systems that May Protect Against Bioterror Threats & Outbreaks

Posted by in categories: biotech/medical, nanotechnology, terrorism

Most traditional vaccines have safety and efficacy issues, whereas particulate vaccine delivery systems—which utilize nano- or micro-particulate carriers to protect and deliver antigens—are efficient, stable, include molecules to bolster immune responses, and minimize adverse reactions due to the use of biocompatible biomaterials.

A new review, titled “Particulate delivery systems for vaccination against bioterrorism agents and emerging infectious pathogens,” summarizes the current status of research efforts to develop particulate vaccine delivery systems against bioterrorism agents and emerging infectious pathogens.

High-Resolution, SWAXS Characterisation of Nanostructures and Nanomaterials with the SAXSpace

Posted by in categories: food, nanotechnology, particle physics

Nanostructured samples and materials can be efficiently and reliable characterized using Anton Paar’s SAXSpace small- and wide-angle X-ray scattering (SWAXS) system. Users can obtain the size, shape, and size distribution of nano-sized samples and particle domains with the help of the SAXSpace. The device is ideally suited for the analysis of colloidal, biological (Bio-SAXS), and isotropic samples.

The SWAXS system also has a wide selection of accurate and versatile sample stages to meet each SAXS application. Easy handling and automatic alignment facilitate smooth operation. With the unique combination of robust design, short measurement time, and high system uptime, the device not only provides superior WAXS or SAXS results but also ensures high sample throughput. These capabilities make SAXSpace ideally suited to explore nanostructure in various materials, including surfactants, pharmaceuticals, proteins, foods, polymers, and nanoparticles.

Trends in Nanomedicine — Technology Benchmarking & Innovator Analysis

Posted by in categories: biotech/medical, health, life extension, nanotechnology

Nanomedicine has been something that many in tech expected to be a critical part of the healthcare landscape for over a decade. I am glad to see how quickly the technology is being adopted as part of bio-medical research and treatments for various diseases, etc.


NEW YORK, April 7, 2016 /PRNewswire/ — Nano-based science paving the precision medicine era.

The continued development of new treatments associated with the demographic trends and public health considerations is remarkable. Nanotechnology has been identified as one most relevant key enabling technologies of the last ten years, significantly impacting on many different biomedical developments in a broad spectrum of applications therapeutics, diagnostics, theranostics, medical imaging, regenerative medicine, life sciences research and biosciences, among many others. In fact, nanomedicine is present in all therapeutic areas, exhibiting a perceptible and extensive impact in the treatment and diagnosis of some most concerned diseases.

Solar Cells Will be Made Obsolete

Posted by in categories: computing, nanotechnology, solar power, sustainability

Rectenna Naval Optical 150928122542_1_540x360
A new kind of nanoscale rectenna (half antenna and half rectifier) can convert solar and infrared into electricity,
plus be tuned to nearly any other frequency as a detector.

Right now efficiency is only one percent, but professor Baratunde Cola and colleagues at the Georgia Institute of Technology (Georgia Tech, Atlanta) convincingly argue that they can achieve 40 percent broad spectrum efficiency (double that of silicon and more even than multi-junction gallium arsenide) at a one-tenth of the cost of conventional solar cells (and with an upper limit of 90 percent efficiency for single wavelength conversion).

Researchers have developed a new and highly efficient method for gene transfer. The technique, which involves culturing and transfecting cells with genetic material on an array of carbon nanotubes, appears to overcome the limitations of other gene editing technologies.

The device, which is described in a study published today in the journal Small, is the product of a collaboration between researchers at the University of Rochester Medical Center (URMC) and the Rochester Institute of Technology (RIT).

Nanoparticles can grow in cubic shape

Posted by in categories: energy, nanotechnology

The efficiency of many applications deriving from natural sciences depends dramatically on a finite-size property of nanoparticles, so-called surface-to-volume ratio. The larger the surface of nanoparticles for the same volume is achieved, the more efficiently nanoparticles can interact with the surrounding substance. However, thermodynamic equilibrium forces nanostructures to minimize open surface driven by energy minimization principle. This basic principle predicts that the only shape of nanoparticles can be spherical or close-to-spherical ones.

Nature, however, does not always follow the simple principles. An intensive collaboration between University of Helsinki, Finland, and Okinawa Institute of Science and Technology, Japan, showed that in some condition iron nanoparticles can grow in cubic shape. The scientists also succeeded in disclosing the mechanisms behind this.

“Now we have a recipe how to synthesize cubic shapes with high surface-to-volume ratio which opens the door for practical applications”, says Dr. Flyura Djurabekova from the University of Helsinki.
