Optical‐fiber bundles [PDF]

open access: yesThe FEBS Journal, 2007
Optical‐fiber bundles have been employed as a versatile substrate for the fabrication of high‐density microwell arrays. In this minireview, we discuss the application of optical‐fiber‐bundle arrays for a variety of biological problems. For genomics studies and microbial pathogen detection, individual beads have been functionalized with DNA probes and ...
