CytoAstra develops a diagnostic platform called the Cytophone that uses in vivo photoacoustic flow cytometry to identify rare disease biomarkers circulating in peripheral blood vessels through intact skin. The device employs a pulse laser to generate sound from biomarkers, which is captured by an ultrasound transducer array attached to the skin. The company focuses on early diagnosis of cancers, infections, and cardiovascular disorders, with particular emphasis on melanoma, malaria, and strokes.
