Under the efficient and compact coupling from optical waveguide, the field highly enhanced and concentrated around gap of gold bowtie structure can trap nano-particle precisely with very strong optical forces compared with most nanophotonic tweezers.
Indirect immunofluorescence (IIF) with HEp-2 cells has been used to detect antinuclear auto-antibodies (ANA) for diagnosing systemic autoimmune diseases. The aim of this study is to develop an automatic scheme to identify the fluorescence pattern of HEp-2 cell in the IIF images. By using the previously proposed two-staged segmentation method, the similarity-based watershed algorithm with marker techniques...
