PDMS filter structures for size-dependent larval sorting and on-chip egg extraction of C. elegans

Martinus Adela Maria Gijs, Hüseyin Baris Atakan, Furkan Ayhan

C. elegans-based assays require age-synchronized populations prior to experimentation to achieve standardized sets of worm populations, due to which age-induced heterogeneous phenotyping effects can be avoided. There have been several approaches to synchro ...
