2025: Product Announcement
Scientists at the Moscow Institute of Physics and Technology (MIPT) have developed a unique domestic lithograph capable of creating three-dimensional microstructures with element sizes up to 150 nm and a resolution of 350 nanometers. This was reported by the press service of the institute in April 2025. Innovative equipment operates on the principle of a 3D printer, which significantly expands its functionality.
According to the developers, one of the key advantages of the new lithograph is the use of ultra-short visible laser pulses, which significantly reduces the cost of equipment and its maintenance. As a material for creating three-dimensional microstructures, optically transparent biocompatible photopolymers are used, specially developed together with the Nizhny Novgorod Institute of Organometallic Chemistry named after G.A. Razuvaev RAS.
Danila Kolymagin, chief designer of the project, head of the Optical Lithography Design Bureau, explained that the device can be used to solve a wide range of problems. With its help, it is possible to create framework systems for growing artificial biological organs with a given geometry. Such scaffolds are made of a special biocompatible polymer on which cells capable of forming tissue are subsequently applied.
In addition, the lithograph allows the development of miniature filters capable of separating different types of cells. In one of the experiments, the researchers have already studied the effect of membrane shape on their ability to pass and trap human kidney embryonic cells (HEK 293).
Danila Kolymagin also noted the prospects for the application of development in the field of photonics. The new lithograph solves an important industry problem - combining emitters, receivers and parts of photonic integrated circuits on a single chip, for the production of which various technologies and materials are traditionally used. This is made possible by forming a polymeric fiber using a new device.[1]
