How Biomimetics Helps Scientists Create Materials With New Properties
Biomimetics is an approach that helps scientists develop new materials and devices based on principles present in nature. We’ve talked about how it’s applied in robotics, but there are many other fields in which it’s also used. For example, physicists working with lasers make use of biomimetics to edit and enhance properties of various materials.

ITMO Scientists Develop Nanostructured Temperature Indicator Based on Carbon Dots and Nanocellulose
Researchers from ITMO’s ChemBio Cluster and University of Toronto discovered a nonlinear dependence of photoluminescence of carbon dots on the composition of a water and dimethyl sulfoxide solvent. The color of the same dot sample changes depending on the polarity of solvent it is placed in. Thanks to this discovery, the researchers were able to develop a portable wide-range (from -68°C to +19°C) temperature indicator, which can be used to control the storage conditions of chemical, pharmaceutical, and food products.

Asymmetry VS Sepsis: Russian-Italian Research Team Developing Optical Sensor for Early Diagnosis
Every year, sepsis takes the lives of approximately six million people around the world. In recent times, it has also become a common COVID-19 complication. In order to treat the disease effectively and quickly, it needs to be diagnosed in the early stages using high-quality sensors. In the fall of 2021, a joint research team from ITMO University and CNR-Nanotec (Italy) won a grant from the Russian Ministry of Science and Higher Education and from the Italian Ministry of Foreign Affairs and International Cooperation for the development of this technology.
