Nucleic acid bio-optrodes have attracted considerable attention in the last few years, partially due to the tremendous amount of genetic information generated from various sequencing efforts but more importantly due to the unique characteristics of DNA oligonucleotides as sensing elements. , 2001). Nucleic acid bio-optrodes have been used in a variety of applications including the detection of pathogenic bacteria. , 2001; Ahn and Walt, 2005). , 2006). , 2005), and potentially whole genome analysis.

This coating prevented light leakage from the fiber’s walls and enabled propagation of the excitation energy down the tapered sides of the nanofiber, bringing maximum light intensity to the fiber tip. The fiber’s uncoated tip surface was then silanized in order to covalently attach anti-BPT antibodies. The final nano bio-optrode tip diameter was 200–300 nm.
