Yesterday, the National Science Foundation (NSF) granted $1 million to the UC San Diego research team for the development of an innovative super-resolution microscope dubbed "metamaterial-enabled structured illumination microscope" (MESIM). Constructed from tailor-made materials, MESIM is anticipated to offer a ten-fold improvement in resolution and over a hundred-fold boost in measurement speed over current top-tier microscopes, UC San Diego reported.
Comprised of a diversified group of experts in microscopy, imaging, machine learning, and biological sciences, the team aims to construct a key instrument to elevate research and education in the biomedical and engineering sectors. The proposed method of MESIM, which adopts "stimulated Raman scattering," that allows for high-detail imaging without dependence on fluorescent markers commonly used in biological microscopy.
MESIM's inventive approach incorporates a special "metamaterial," a synthetic composite element designed to intensify light into more concentrated beams. This technological leap enhances MESIM's ability to perceive the diffusion of photons, dubbed "Raman scattering." By significantly increasing photon scattering, researchers are able to delve deeper into molecular behavior and refine real-time image reconstruction with burgeoning computer algorithms and machine learning packages.
At the foundation of MESIM's extraordinary capabilities is the "stimulated Raman scattering imaging" method, which lets researchers meticulously explore molecular behavior at breakneck speeds. Co-principal investigator Mark Ellisman believes that this advanced technology can divulge foundational insights into molecular dynamics and microscopic processes, from how water molecules are structured to understanding the link between cell metabolism, microbiology, neuroscience, aging, and diseases.
The embodiment of this technology in MESIM could usher in therapeutic breakthroughs and superior tools for biomedical research, as well as present prospects for undergraduate and graduate students within and beyond UC San Diego. Situated within the Qualcomm Institute's Atkinson Hall at UC San Diego, MESIM is poised to encourage campus-wide collaboration.
Moreover, MESIM promises significant contributions to current neuroscience research. The National Center for Microscopy and Imaging Research (NCIMR), a leading microscope and imaging research center, plans to utilize MESIM's distinct imaging capabilities to tackle neuroscience questions concerning cerebral cell diversity and neurocartography. This could radically overhaul attempts to understand the human mind and its numerous complexities.
