Mobile Phone Microscopy

Juli 23, 2009

Researchers at the University of California, Berkeley, US have developed the CellScope – a new microscope that can be attached to a common mobile phone with a camera to take color images of microorganisms. The CellScope consists of compact microscope lenses fitted in a holder, which is positioned in front of the mobile phones camera. By using an off-the-shelf phone with a 3.2 megapixel camera, the researchers were able to achieve a spatial resolution of 1.2 micrometers. In this way they were able to capture bright field images of Plasmodium falciparum, the parasite that causes malaria in humans and sickle-shaped red blood cells. They were also able to take fluorescent images of Mycobacterium tuberculosis, the bacterium that causes TB in humans. The development of CellScope moves a major step forward in taking clinical microscopy out of specialized laboratories and into field settings for disease screening and diagnoses. „The same regions of the world that lack access to adequate health facilities are, paradoxically, well-served by mobile phone networks,“ said Dan Fletcher, UC Berkeley associate professor of bioengineering and head of the research team. „We can take advantage of these mobile networks to bring low-cost, easy-to-use lab equipment out to more remote settings.“

MIT and INL Launch Research Collaboration

Juli 21, 2009

The International Iberian Nanotechnology Laboratory (INL), Braga, Portugal and the Massachusetts Institute of Technology (MIT), MA, US have announced a new collaboration that will enrich each institution’s research activities in nanoscience and nanotechnology. The two institutions will create MIT-INL, a new education and research enterprise focusing on nanotechnology. The collaboration will create 10 senior research positions for scientists who will launch a new nanotechnology research agenda, and it will enable approximately $35 million (€25 million) of new sponsored research with MIT in its first five years.

State-of-the-Art Geosciences Laboratory Opened

Juni 29, 2009

An advanced science laboratory has officially been launched on June 26, 2009 at the University of Monash, Victoria, Australia by the Minister for Innovation, Industry, Science and Research Kim Carr. The $1 million Earth Sciences teaching laboratory will provide students with the latest in high-tech learning, giving them access to next-generation computer modelling and microscope technology. Head of Geosciences School Professor Ray Cas said the laboratory had the capacity to teach at a microscopic scale via the linking of microscopes with the smart screens. „The laboratory is the most advanced facility of its kind in Australia and the technology it employs is at the cutting-edge internationally,“ Professor Cas said.

Molecular Light Switches for Higher Resolution

Mai 29, 2009

The “Superresolution” research network, founded by the German Ministry of Education and Sciences, demonstrated a new widefield microscopy technology with resolutions better than 20 nanometers. The method is based on special dyes, which’s fluorescence can be optically and reversibly switched on and off in aqueous solutions. The dyes are bond to cellular structures by using a functional group. By switching the dyes on and off, the fluorescence emission is separated in time until only those dye molecules fluoresce that have enough distance to allow their localization as single molecules. After several thousand switching cycles, a total image is constructed (dSTORM – direct stochastic optical reconstruction microscopy). Involved in the project were the work groups of Prof. Dr. M. Sauer and Prof. Dr. J. Mattay (University of Bielefeld, Germany ), Prof. Dr. K.-H. Drexhage (University of Siegen, Germany), Prof. Dr. J. Enderlein (University of Goettingen, Germany), and Prof. Dr. S. Hell (Max Planck Institute of Biophysical Chemistry, Goettingen, Germany).

Strengthening the Research and Education Network

März 13, 2009

Microscope designer Leica Microsystems and the European Molecular Biology Laboratory (EMBL) have signed a corporate partnership agreement whereby Leica Microsystems becomes a founder partner of the EMBL Advanced Training Centre scheduled to be completed in September 2009. Besides its financial involvement, the company will provide EMBL with Leica systems and will support events for the international scientific community. In return, Leica will be granted access to the first-class facilities of the molecular biology research institute to run product and application training courses.

World of Photonics

Februar 13, 2009

In June 2009, two international events for optical technologies in Europe will once again take place in Munich, Germany. From June 15-18, the New Munich Trade Fair Centre will host the exposition „LASER World of PHOTONICS“ and from June 14-19 the „World of Photonics Congress“ will be held at the International Congress Centre Munich. Both events address to representatives from research, the laser and optoelectronics industries, professionals involved in medicine and technology as well as physicists, chemists, doctors, engineers, system designers, retail companies and service-providers. This year, the trade show and the congress have expanded their offerings for biophotonics and life sciences. The trade show is setting up an exhibition focus area dedicated to the subject of biophotonics. The World of Photonics Congress will present the field of biophotonics at the „Medical Laser Applications“ conference. Experts in the field of lasers in medicine, optical diagnostics, high-end endoscopy and minimally invasive surgery will give practically orientated presentations.
