Health and Safety Training for Immigrant Dairy Workers in the Upper Midwest.

This project implemented Seguridad en las Lecherías, an award-winning, bilingual (Spanish and English), 5-module curriculum approved by the Occupational Safety and Health Administration. The intervention aimed to increase safety knowledge among immigrant dairy workers, encourage a safety culture, and identify challenges faced by the dairy farming community in Minnesota and South Dakota. A total of 360 Hispanic immigrant workers from 19 participating dairies were trained.

Resistive-Pulse Sensing Coupled with Fluorescence Lifetime Imaging Microscopy for Differentiation of Individual Liposomes.

Characterization of individual biological nanoparticles can be significantly improved by coupling complementary analytical methods. Here, we combine resistive-pulse sensing (RPS) with fluorescence lifetime imaging microscopy (FLIM) to differentiate liposomes at the single-particle level. RPS measures the particle volume, shape, and surface-charge density, and FLIM determines the fluorescence lifetime of the fluorophore associated with the lipid membrane.

Advancements and Applications of Conjugated Polyelectrolytes and Conjugated Oligoelectrolytes in Bioanalytical and Electrochemical Contexts.

In the past decade, conjugated oligoelectrolytes (COEs) and conjugated polyelectrolytes (CPEs) have emerged at the forefront of active materials in bioanalytical and electrochemical settings due to their unique electronic and ionic properties. These materials possess π-conjugated backbones with ionic functionalities at the ends of their side chains, granting them water solubility and facilitating their processability, exploration, and applications in aqueous environments. In this perspective, the basis for evaluating their figures of merit in selected bioanalytical and electrochemical contexts will be provided and contextualized.
