Conventional methods for foodborne pathogen detection are time-consumin g and laborious due to the requirement of a series of processes including cell enrichment\, isolation and morphological identification. Therefore\, the demand for rapid\, sensitive\, inexpensive and convenient approaches t o detect foodborne pathogenic bacteria has emerged in recent years. Among those new approaches\, microfluidic chip-based detection has generated gro wing interests because of their miniaturized size\, improved sensitivity a nd reduced detection time. To this end\, our research group have been work ing on strategies to enhance detection signals using aptamers to effective ly capture detection targets and subsequently enhance detections by rollin g circle amplifications (RCA). In this seminar\, I will talk about our rec ent efforts to surface modify microfluidic channels in order to improve ta rget capturing efficiencies and discuss our approaches to intensify signal s for sensitive detections.\n\nSpeaker(s): Dr. Xudong Cao\, \n\nOttawa\, O ntario\, Canada\, Virtual: https://events.vtools.ieee.org/m/256542 LOCATION:Ottawa\, Ontario\, Canada\, Virtual: https://events.vtools.ieee.or g/m/256542 ORGANIZER:m.abdelazez.ca@ieee.org SEQUENCE:2 SUMMARY:IEEE Ottawa EMBS - Sensitive detection of foodborne pathogenic bact eria using microfluidic devices URL;VALUE=URI:https://events.vtools.ieee.org/m/256542 X-ALT-DESC:Description: <br /><p>Identification and quantification of foodb orne pathogens are becoming increasingly important to public health and fo od safety since the majority of foodborne illnesses and deaths are caused by pathogenic bacteria.
