Currently, the most widespread technique for detecting Cryptosporidium oocysts in water samples is based on fluorescence microscopy in which a sampling step is needed. The oocysts are then separated from the water and other contaminants using specialized filters, after which they are stained with antibody-conjugated fluorescent dyes and detected in a fluorescence microscope. Other conventional methods employ immunological and polymerase chain reaction techniques for detecting oocysts . Although there is room for improved efficiency of these methods, for example, by utilizing autofluorescence from the oocysts, these methods in their current form suffer from drawbacks such as being labor-intensive, having high costs, and long detection times.
