Imaging has rapidly become a defining tool of the current era in biological research. But finding the right method and optimizing it for data collection can be a daunting process, even for an established imaging laboratory. Cold Spring Harbor Protocols is one of the world's leading sources for detailed technical instruction for implementation of imaging methods(http://cshprotocols.cshlp.org/cgi/collection/imaging_microscopy_general), and the November issue...

Chemists from the Jena University improve the process for the fabrication of sharp atomic force microscopy tips Scientists from the Friedrich-Schiller-University Jena (Germany) were successful in improving a fabrication process for Atomic Force Microscopy (AFM) probe tips. Atomic Force Microscopy is able to scan surfaces so that even tiniest nano structures become visible. Knowledge about these structures is for instance important for the development of new materials and carrier systems for...

For their look into the nanoworld, the Jlich researchers used a scanning tunneling microscope. Its thin metal tip scans the specimen surface like the needle of a record player and registers the atomic irregularities and differences of approximately one nanometer (a billionth of a millimeter) with minuscule electric currents. However, even though the tip of the microscope only has the width of an atom, it has not been able so far to take a look inside molecules."In order to increase the...

Researchers at JILA have demonstrated the use of infrared laser light to quickly and precisely heat the water in "nano bathtubs""”tiny sample containers"”for microscopy studies of the biochemistry of single molecules and nanoparticles. Described in a new paper,* the JILA technique is faster, more controllable, and less prone to damaging expensive optics or accidentally altering chemistry than conventional methods using electric currents for bulk heating of microscope stages,...

Conventional wisdom holds that optical microscopy can't be used to "see" something as small as an individual molecule. But science has once again overturned conventional wisdom. Secretary of Energy, Nobel laureate and former director of the Lawrence Berkeley National Laboratory (Berkeley Lab) Steven Chu led the development of a technique that enables the use of optical microscopy to image objects or the distance between them with resolutions as small as 0.5 nanometers "“ one-half of one...

On a quest to discover new states of matter, a team of Princeton University scientists has found that electrons on the surface of specific materials act like miniature superheroes, relentlessly dodging the cliff-like obstacles of imperfect microsurfaces, sometimes moving straight through barriers. The Princeton work represents the first time such behavior of electrons has been tracked and recorded, and hints at the possibilities of speeding up integrated circuits that process information by...

PORT MATILDA, Pa., June 7 /PRNewswire/ -- QBC Diagnostics is pleased to announce the release of the SureFocus Microscope Slide, a breakthrough in the detection of tuberculosis bacteria. The SureFocus slide is a high-grade glass microscope slide that is printed with a patent pending, crosshair-styled smear guide. The guide contains a dye that fluoresces under the same light wavelengths that excite Auramine stains, which are used to stain tuberculosis Acid Fast Bacilli (AFB) for review...

Scalable and reusable optical detection system boasts the sensitivity of a large microscope in a much smaller, cheaper package With a silicone rubber "stick-on" sheet containing dozens of miniature, powerful lenses, engineers at Harvard are one step closer to putting the capacity of a large laboratory into a micro-sized package. The marriage of high performance optics with microfluidics could prove the perfect match for making lab-on-a-chip technologies more practical. Microfluidics, the...

Photothermal technique provides new way to track nanoparticles Stephan Link wants to understand how nanomaterials align, and his lab's latest work is a step in the right direction. Link's Rice University group has found a way to use gold nanorods as orientation sensors by combining their plasmonic properties with polarization imaging techniques. That may make it possible to see and perhaps track single nanoparticles over long periods. It would give researchers new information about materials,...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
