Cloud Swifter v1.0: Autonomous Atmospheric Microplastic Sampling Aircraft
AI summary Read the abstract
Researchers designed an autonomous UAV platform called Cloud Swifter that combines endurance flight with multi-stage particulate filtration to collect and validate atmospheric microplastic samples, repositioning airborne microplastic sampling from speculative cleanup concepts to experimentally verifiable environmental monitoring.
Cloud Swifter v1.0 is a physically grounded autonomous airborne system designed to measure atmospheric microplastics. The platform integrates endurance UAV flight, multi-stage particulate filtration, and post-flight laboratory validation. This work reframes airborne filtration from speculative cleanup concepts toward experimentally verifiable environmental sampling. The system is designed to map atmospheric microplastic gradients, collect validated samples, and support the development of future monitoring infrastructure. This package includes a Nature-style manuscript, system blueprint, validation plan, and supporting materials.

Measuring atmospheric microplastic composition and occurrence from an uncrewed aerial system
AI summary Read the abstract
Researchers used a drone to collect air samples 100 meters above the ground at two sites in Colorado. Microplastic particles were confirmed in about 14% of the small airborne particles tested, many resembling material from traffic. This small test study shows drones can be used to sample microplastics in the air.
Measuring atmospheric microplastic composition and concentration from an uncrewed aerial system
AI summary Read the abstract
Researchers flew a drone 80 to 100 meters high at two sites in Colorado to collect tiny airborne particles. Using microscopes, they found microplastics at both locations, with most particles made of mixed materials resembling traffic-related debris. This early test shows drones can be used to measure microplastics in the air.
