Label-free, Fluorescenece Detection of DNA Nanoparticle Scaffolds

Kell A.J., Tan S., Charlebois I., Boissinot M., Simard B., National Research Council, CA

We have developed a nanoparticle-based DNA biosensor that can detect unlabelled ssDNA with good sensitivity (picomolar concentrations). The biosensor makes use of the optical changes of a cationic polymer interacting with ssDNA versus that of [...]

Multifunctional nanoparticle platforms for pathogen diagnostic applications

Kell A.J., Paquet C., Simard B., National Research Council, CA

Infectious diseases and bioterrorism are of tremendous global concern, and our group is interested in developing superparamagnetic nanoparticle platforms that can aid in the magnetic extraction/concentration and detection of harmful pathogens. This has led to [...]
