Rahman B, Soni P, Saroyia AP, Schenkenfelder W, Vanapalli SA.Microfluidic well plates integrated with passive nematode culture chambers for multiplexed chemical toxicity assays in C. elegans.Lab on a Chip. 2026 Apr 14. Online ahead of print.PI: S.A. VanapalliNote: From the abstract: “Whole-organism toxicity assays are essential for evaluating the safety of chemicals, but mammalian models remain costly and low throughput, contributing to a global backlog of untested chemicals. The micro-organism C. elegans has emerged as one of the new approach methodologies (NAMs) modelling toxicological responses across multiple interacting tissues, with advantages of human-relevant biology and cost-effectiveness. However, existing technologies for C. elegans toxicity testing are limited by poor compatibility with long-term chemical exposure, lack of multiplexibility, and inability to dynamically modulate chemical exposure over time. Here, we present a novel microfluidic platform, passive nematode culture chambers (PNCs) integrated into well plates â€“ where micropillar arenas housing crawling or swimming C. elegans have fluid communication with the surrounding medium, enabling consistent nutrient access and long-term viability.”

OpdensteinenNote: From the abstract: “Developing plant adhesives opens opportunities for studying and optimizing plant growth through precision pesticide and nutrient delivery, plant health monitoring, and human-plant interaction. However, diverse and changing topologies and chemical compositions of plants during growth present challenges in designing effective and universal adhesives. In this study, we address this challenge by developing a gel composite consisting of a biopolymer that enables dynamic covalent bonding with plant surfaces and cross-linked polyacrylamide, which provides adaptability.”
