This research shows that 20 μm of the LAF is the most appropriate modification layer thickness.

A team of McGill University researchers has developed a cost-effective, high-throughput technology for detecting nanoplastics and microplastics in the environment.

These particles are pervasive, posing health and environmental risks, yet detecting them at the nanoscale has been difficult. The 3D-printed HoLDI-MS test platform overcomes the limitations of traditional mass spectrometry by enabling direct analysis of samples without requiring complex sample preparation. The researchers say it also will work for detection of waterborne plastic particles. HoLDI-MS stands for hollow-laser desorption/ionization mass spectrometry.

A new study led by Georgetown University’s Institute for Soft Matter Synthesis and Metrology (ISMSM) researchers, Prof. Emanuela Del Gado, Dr. Mauro L. Mugnai and Rose Tchuenkam Batoum, titled “Inter-Species Interactions in Dual, Fibrous Gel Enable Control of Gel Structure and Rheology,” published in Proceedings of the National Academy of Sciences (PNAS), reveals a powerful way to fine-tune the structure and stiffness of soft gels. These are materials found in everything from biomedical devices to synthetic tissues.
