In 2018, very large organic molecules were discovered in ice particles on Saturn's moon Enceladus. It is still unclear whether they indicate the existence of life or were created in some other way. A recent study could help to answer this question. It is possible, that conditions that support or maintain life in extraterrestrial oceans could leave molecular traces in grains of ice.
Developing high-performance gas sensors for the detection of lung cancer markers at low concentrations is a crucial step towards achieving early lung cancer monitoring through breath tests. Metal oxide semiconductors (MOS) have long been sensitive to volatile organic compounds (VOCs), demonstrating excellent performance characteristics.
