Abstract: Many conventional biochemical assays are performed using populations of
cells to determine their quantitative biomolecular profiles. However, population averages
do not reflect actual physiological processes in individual cells, which occur either on short
time scales or nonsynchronously. Therefore, accurate analysis at the single-cell level has
become a highly attractive tool for investigating cellular content. Microfluidic chips with
arrays of microwells were developed for single-cell chemical lysis in the present study.
The cellular occupancy in 30-μm-diameter microwells (91.45%) was higher than that
in 20-μ
