Microplastic False Positives: Your Dry Gloves Are Ruining Science

Ever tried to find microplastics in a sample and ended up finding only your own skin flakes? You're not alone. Researchers from RSC Publishing have finally confirmed what lab techs have whispered for years: dry gloves are a false-positive factory.

Turns out, even a gentle touch with a dry nitrile glove sheds microscopic particles that masquerade as microplastics. It's like searching for a needle in a haystack, but the haystack keeps shedding needles. The solution? Moisten gloves before use or ditch them for clean tweezers.

Ironically, many protocols still ignore this, so researchers have been publishing data where half the "microplastics" are just — excuse the pun — their own digits. Devs who've debugged CI failures will feel the pain: you're hunting a bug in code, but it's in the CI config.

So if your microplastic experiment shows suspiciously high numbers, maybe check if you wore dry gloves. Or at least wet them — like cookies in milk, but for science.

METABYTE's take: We're not lab scientists, but in dev we know the value of eliminating false positives — whether in tests or data. Just remember to check your code's "gloves": linters and static analysis have your back.
