Researchers in the US have created a new "soft" form of matter, the living liquid crystal. These are living bacteria that swim in a non-toxic, water-based liquid crystal.
This dynamic interaction between microorganisms and the crystal is what gives the material new properties. The innovative "hybrid" material could be used in various practical applications in the future, including as a biosensor for the early diagnosis of various diseases.
Researchers from Kent State University in Ohio and Argonne National Laboratory in Illinois, led by Shuang Chu and Igor Aranson, made the announcement at the annual meeting of the American Biophysical Society, held in San Francisco.
As a biomechanical hybrid, the living liquid crystal is constantly moving and takes on various shapes depending on the external stimuli it receives. It also stores energy, as living organisms do, in order to move. It also has significant optical properties, in combination with a microscope, which makes it particularly easy to detect bacteria and other microorganisms.
Living liquid crystals are a promising medium that will help scientists better observe the reactions of molecules and microorganisms and their interactions at the micro- and nanoscale. Precisely for this reason, the new form of matter will be useful for creating new types of diagnostic devices and biosensors that will better "see" biological processes, such as the development of cancer or an infection in the body.
