![]() In a past study, the researchers showed in lab tests that the device could capture the bacteria responsible for strep throat. This flattened end is covered with isomalt candy, allowing for saliva to easily flow into the groove as the lollipop is eaten. At first glance, Cand圜ollect looks like most lollipops, except for its spoon-like stick with a spiral-shaped groove carved into the top. Previously, Sanitta Thongpang, Ashleigh Theberge, Erwin Berthier and colleagues developed their own lollipop collection device dubbed Cand圜ollect. Gathering the necessary amount of saliva can be somewhat gross, though, which is why some scientists are looking to make the process more enjoyable by combining it with the equally drool-filled, yet much more pleasant, experience of enjoying a lollipop. Because this type of sample can be collected directly by a patient, the technique is popular for at-home testing and saw expanded use during the COVID-19 pandemic. A less-gag-inducing method is saliva sampling, in which technicians analyze a patient’s spit with methods such as quantitative polymerase chain reaction (qPCR). Throat swabs are commonly used to collect samples for the diagnosis of a wide variety of illnesses, including strep throat. Study participants also preferred the candies over conventional collection systems. Researchers publishing in ACS’ Analytical Chemistry have shown, for the first time, that a lollipop-based saliva collection system can capture bacteria from adults and remain shelf-stable for up to a year. A lollipop might be a sweet reward for a kid who’s endured a trip to the doctor's office, but now, this candy could make diagnostic testing during a visit less invasive and more enjoyable. ![]()
