Easy swabs and vials play essential roles in transporting blood, saliva and different fluids throughout medical lab checks. Samples on cotton swabs dry out quickly, nonetheless, and vials can require a further switch step earlier than evaluation. Now researchers have discovered {that a} felt marker’s fibrous tip—with out ink, in fact—can double as an efficient, long-lasting sampler.

Physicist Igor Popov and his workforce on the Moscow Institute of Physics and Expertise purchased alternative suggestions, designed to carry inks for lengthy durations with out drying, which can be utilized in a preferred business marker. After soaking these extremely porous suggestions in blood or saliva spiked with the painkiller acetaminophen, the researchers efficiently examined their MacGyvered samplers to establish the drug and decide its focus—even after seven days of room temperature storage. Popov says such samplers would work greatest for checks to detect medicine and hormones that don’t break down rapidly. “This expertise could possibly be utilized for medical investigations in tough situations, corresponding to amenities far-off from giant cities,” he provides. The software’s use is detailed in Acta Astronautica and in Molecules.

One other potential implementation: area journey. Popov says samplers used to check astronauts on the job should be compact, light-weight and usable with out intensive coaching. Samples should even be simply storable for return to Earth; area station astronauts presently use vials that take up beneficial freezer area.

The marker concept “is a brand new utility I’ve by no means seen for this objective earlier than,” says College of South Carolina chemist Susan Richardson, who was not concerned within the research. She provides that future analysis ought to check how lengthy compounds of curiosity stay viable in bodily fluids corresponding to saliva, which could host microorganisms that degrade them.

Subsequent the researchers will evaluate varied marker sorts to see which qualities contribute to raised pattern storage—testing nibs of each composition, form and measurement.
