In this study, Dr. Diana and her team of researchers present an inexpensive method suitable to develop microfluidic devices used in the biomedical field. Even though soft-lithography is the commonly used method to fabricate biomedical microdevices, it is still a time-consuming and expensive method. The growth in developing milling tools that are smaller than 100 µm, has resulted in the use of micromilling machines to produce microfluidic devices that have the ability to execute the cell separation process.
Nanolive is planning to launch a new microscope, also know as the 3D Cell Explorer, on December 14. This new microscope will help to observe living cells in 3D. For the very first time, this invention will enable researchers to examine the inside of living cells without causing any damage to them. Preventing the cells from being stained, and eliminating the need to develop the sample far in advance. The invention will be displayed for the first time at the world’s biggest cellular biology conference in San Diego, U.S.
When life gives you lemons, make lemonade. At Oak Ridge National Laboratory and Uppsala University, researchers have done the scientific equivalent by using, rather than eliminating, flaws inherent to electron microscopy to create probes for performing novel atomic-level spectroscopy.
Think of it as a microscopic movie: A sequence of X-ray images shows the explosion of superheated nanoparticles. The picture series reveals how the atoms in these particles move, how they form plasma and how the particles change shape.
A new method to develop complexly arranged tiny objects combined with microspheres has been discovered by a group of scientists at IBM Research Zurich and ETH Zurich. These tiny objects are only a few micrometres in size and are formed in a modular manner, allowing their design to be programmed so that every single component displays a wide variety of physical properties. This is followed by introducing the micro-objects into a solution through a very simple step after the fabrication process.
In a new study recently published in Nature Nanotechnology, researchers from Columbia Engineering, Cornell, and Stanford have demonstrated heat transfer can be made 100 times stronger than has been predicted, simply by bringing two objects extremely close—at nanoscale distances—without touching. Led by Columbia Engineering’s Michal Lipson and Stanford Engineering’s Shanhui Fan, the team used custom-made ultra-high-precision micro-mechanical displacement controllers to achieve heat transfer using light at the largest magnitude reported to date between two parallel objects.
As the sizes of computer chips in electronic devices continue to shrink, traditional measurement tools (e.g., microscopes utilizing visible light) are no longer capable of examining surface features, which can be just tens of nanometers. In order to examine these tiny features, researchers use tools such as the critical dimension atomic force microscope (CD-AFM), which measures features by dragging its ¡Ö10 nm tip across the subject¡¯s surface much like a record player needle pulling across a record¡¯s grooves.
Scientists from the University of Copenhagen and the Paul Scherrer Institute in Switzerland have, for the first time, created a 3D image of food on the nanometer scale. The method the scientists used is called Ptychographic X-ray computed tomography. It has promising prospects as a more detailed knowledge of the structure of complex food systems could potentially save the food industry large sums of money and reduce food waste that occurs because of faulty production.
Single molecules can be observed in detail using special microscopes. However, these ultra-high resolution instruments require an image processing step to process the raw image data to obtain an image. A new open source software solution, capable of rapidly and efficiently processing such raw image data has been developed by the Members of the Biomolecular Photonics Group at Bielefeld University for an ultra-high resolution fluorescence microscope used for biophysical research.
Real-time, in situ monitoring of the self-assembly of nanocrystal structures has been made possible by a team of researchers using a combination of technologies, including controlled solvent evaporation and synchrotron X-ray scattering, paving the way for researchers to gain insights into the mechanisms behind the self-assembly of these structures.
