Called interscale mixing microscopy (IMM), the technique can obtain details in these structures much smaller than the wavelength of light (known as the diffraction limit)-so it could be useful in developing new vaccines against pathogens and novel drug drugs to fight diseases. Prof. Viktor Silicon Window Podolskiy, the key private investigator for the UMass Lowell team, explains Sapphire Window anytime an object is smaller than the wavelength of light, you cannot resolve the object's size, shape, or structure-the team's technique, however, is designed to go beyond the diffraction limit. "Subwavelength imaging with IMM can potentially be taken to obtain the colors, or spectra, of small objects such as bacteria, trojans, and nanoparticles, inch Podolskiy explains. "By knowing their color signatures, we can rapidly identify and characterize the objects and determine their precise chemical arrangement. inch The IMM technique uses a conventional optical microscope and clever signal processing to decode the object's properties based on the rating of light that gets spread by the object in close proximity to a special, carefully decided plate called a diffraction grating. The researchers showed that a single rating with ZnSe crystal the grating may be enough to decipher with great precision the positioning, LBO crystal size, and optical array of the object. Deciphering electron microscopes (SEMs) can typically resolve details down to 5-10 nm. Right now, the IMM is constrained to about 60 to 70 nm. "Although our technique is not yet as powerful, a brand-new deciphering electron microscope can cost anywhere from hundreds of thousands of dollars to a million, inch says Christopher Roberts, a PhD student in physics who conducted the project's data processing and analysis. But the research team's IMM, he says, can be retrofitted to older, existing research optical microscopes, thereby saving universities and companies a lot of money.
