In Moscow, produced the world’s first probe microscope with full control via the Internet

Under the heading "Innograd" NTV talking about the Moscow company "Center for Advanced Technologies". Its main products — scanning probe microscopes called "FemtoScan." With such example, biological cells and tested bacterial DNA.

Probe microscope, explains the company, works almost like a gramophone. He also has a tiny needle that slides on the subject. Scientists recorded as the position of the needle of this, and see the image of the object surface which can distinguish atoms and molecules.

An important feature of the "FemtoScan" that he was the world’s first probe microscope, which can be fully controlled via the Internet. The production of these devices became interested in the company "RUSNANO". It will help the center to expand production, reports NTV.

"Center for Advanced Technologies" has become one of the two project companies of RUSNANO, who took part in a meeting with representatives of the international publishing company Nature Publishihg Group (NPG) and the editors of regional editions of the popular science magazine Scientific American from 11 countries. (The second company — JSC "OptoGaN")

"FemtoScan" is a scanning probe microscope, which first implemented the technology in the world of remote control of the instrument and data analysis via the Internet. This allows for full-scale measurements from any computer connected to the local network or the Internet, with an unlimited number of authorized network users can access the data of the experiment in real time, and carry out independent analysis, processing, and construction of three-dimensional images.

The microscope allows measurements in air and in liquid media. It is designed for basic and applied research, as well as for the organization of a pilot distance education students in the field of practical nanotechnology.

Implemented 50 different modes of scanning probe microscopy, including:
contact atomic force microscopy
resonance atomic force microscopy
non-contact atomic force microscopy
Scanning microscopy friction
Scanning tunneling microscopy
tunneling spectroscopy
Scanning microscopy resistive
electrostatic microscopy
Magnetic Force Microscopy
mapping of the surface force

And also:
Optical microscopy with data transmission through the Internet
Measurements in air and in liquid
Adjustable heating temperature sample

The company also produces unique cantilevers Klimov, with fantastic resolution up to 1 nm (Cantilevers — needle scanning probe microscopes, which should be comparable in size with the test object).


Dmitry wedges, Institute of Bioorganic Chemistry. Shemyakin and Ovchinnikov, Russian Academy of Sciences, Moscow, Russia "The unique resolution was demonstrated resonant atomic force microscopy of DNA molecules, using the latest graphite probes to the edge ~ 1nm. Probes were manufactured increasing carbon spikes by the plasma at the vertices conventional silicon probes. Probes were grown on conventional silicon ends of probes are commonly used in atomic force microscopy. TEM micrograph of one such probe (Figure a) shows variously oriented carbon spikes silicon grown on the end of the probe. Most stud with catching edge ~ 1 nm can be used in scanning probe microscopy. The top of the needle silicon probes, ispolzuyuschihsyav resonance method, generally in the range of 10-20 nm. Resolution resonance imaging method above, then the size of the edge of the needle corresponds to the fact that the contact area of the needle and the sample depend not only on the size of the needle, but also the mechanical properties of the sample and the tip. Images of the DNA molecules obtained by the super-critical graphite probes and conventional silicon showed that excellent structural resolution was achieved only by using such sharp diamond graphite probes (Figure b). Images taken by these probes reproduce a spiral structure and Z-like loops in DNA molecules.
Conductivity actual DNA of course depends on many factors, such as the contacts on the electrodes [1] Procedure offset [2]. Various types of loops or kinks that are not seen with conventional silicon probes can also reduce conductivity DNA. Images of DNA obtained using graphite probes (Figure b) have a very high resolution
