French-based Nanolane has recently created easy-to-use Sarfus Mapping Lite, a plug-in piece of apparatus, the main components of which are a set of Surf microscope slides, step-height standards and a powerful piece of software. Sarfus Mapping Lite fits with all optical microscopes that use reflected light. Thanks to the technology developed by Nanolane, what has remained invisible to an optical microscope for so long is now revealed clearly.
Surf slides replace ordinary microscope glass slides and are where users deposit samples. The users then handle the optical microscope as usual, apart from the fact that the contrast enhancement brought about by Surf is such that they can see nano-objects in the shape of films, tubes or particles directly through eyepieces, i.e. with the naked eye.
The data conversion software included in the Sarfus Mapping Lite package takes a Charged Coupled Device (CCD) camera-obtained 2D colour image and provides a 3D thickness map of a nanometric sample. To do so, the optical instrument, i.e. the combination of the optical microscope and colour camera, is calibrated. This calibration occurs thanks to a series of nanometric step-height standards that are traceable to the ISO 17025 standard. These standards mean that a detection limit, which can be as high as 0.1nm (instrument dependent), is guaranteed.
Up until now, Surf-slide users were able to sense and image nanometric objects, such as nanotubes, nanowires, DNA strands, and nanoparticles. With Sarfus Mapping Lite, they will also be able to measure thin films and surface treatment of items with nanometric thickness.
The benefits one gains from adding Sarfus Mapping Lite to a microscope, as compared to the current nanocharacterisation or imaging tools, are, above all, related to its excellent accessibility and user friendliness.
Real-time image acquisition makes it possible to record fast dynamic phenomena, depending on the camera's capacities. A selectable field of view, ranging from a few µm² to several mm², depending on magnification, gives users the flexibility to study their samples globally. This global studying is useful for locating regions of interest (ROIs). The selectable field of view also allows samples to be studied locally, so as to investigate micro- to sub-micro-details. Additionally, the viewing technique is non-contact in nature and, therefore, truly non-destructive.
Applications of Sarfus Mapping Lite are many, from thin-film characterisation (for organics, inorganics, liquid crystals and lithography) to biological systems (such as biochips and biofilms), among many others. More fundamental research-related applications include nanopatterns, Langmuir-Blodgett films, and self-assembled monolayers(SAMs), for example.
Nanolane, the nanotechnologies department of Eolane of France, develops and sells scientific instruments and scientific-related consumables in the field of nanotechnology.
Eolane is an electronic manufacturing services (EMS) business whose 2,400 members of staff, working for its many subsidiaries, generate an annual turnover of about €300 million. Eolane operates in a range of complementary fields encompassing technology and industry.
Nanolane's Sarfus Mapping Lite is a package that includes a number of items, with, in particular, a set of Surf slides, some step-height standards, and a powerful piece of software. It fits with all optical microscopes that use reflected light, allowing what has remained invisible to an optical microscope for so long to be clearly revealed.

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.
The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...
Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.
The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...
In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.
In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
