Researchers have developed a new nanolithography technique claimed to be less expensive than other approaches and that can be used to create technologies with biomedical applications.
‘Among other things, this type of lithography can be used to manufacture chips for use in biological sensors that can identify target molecules, such as proteins or genetic material associated with specific medical conditions,’ said North Carolina State University’s Dr Albena Ivanisevic, co-author of a paper describing the research.
According to a statement, the new technique relies on cantilevers made from silicon strips that are 150-microns long. The cantilevers can be tipped with spheres made of polymer or with naturally occurring spores. The spheres and spores are coated with ink and dried. The spheres and spores are absorbent and will soak up water when exposed to increased humidity.
