Abstract
A microwell for enzyme-linked immunosorbent assays has a concavely curved, circumferential sidewall, a flat optical bottom and a top lip, including smooth transitions between the top lip, concave sidewall and flat bottom. This shape minimizes the tendency of fluid to cling to the well for washing efficiency and maximizes a vertical optical path length of fluid in the well for improved optical determination.
