The invention of microscopes has done wonders for the science. Magnifying of objects as minute as microorganisms makes experiments simple and easy. Now the researchers have formulated a way to make microscopes more magnificent.
The researchers at the Australian National University (ANU) have developed a methodology through which microscopes can magnify 20 times more than usual.
A more magnificent nature of the new form of microscopes will allow the scientists to see and identify substances minuscule as virus.
The researchers explain the new methodology involves laser beams that cool a nanowire probe to 265 degree Celsius. The nanowires used in the experiment are 500 times finer than human hair.
Explaining the technique of nanotechnology, researchers said it allows for extreme sensitivity and hence the investigation using microscope becomes even more accurate.
“The level of sensitivity achieved after cooling is accurate enough for us to sense the weight of a large virus that is 100 billion times lighter than a mosquito,” said Dr. Ben Buchler, a researcher at the Research School of Physics and Engineering at ANU.
Researchers say the findings act as a major breakthrough in conducting of the experiments as it will further improve the resolution of atomic-force microscopes which are used to measure nanoscopic matter and tiny substances between molecules.
Everything comes with strengths and weakness and this new probing method is not an exception. Scientists say the method too has flaws. The nanowires used in this methodology are so tiny that their functions can be easily disrupted by vibration.
“The probe vibrates even at room temperature and makes measurements noisy,” co-author Prof. Ping Koy Lam said.
But he said that this noise can be curbed through shining cooling lasers on it that counters the thermal interruption.
