PHD. SUBJECT 

3D design of a microfluidic cell for the rapid bio-detection of pathogen targets

 

Summary

The emergence of microfluidics and nanotechnologies has enabled both new capabilities and instrument sizes practical for point-of-care technologies integrating microfluidics in biosensor technology offers new opportunities for future biosensing applications including portability, real-time detection, improved accuracy, increased sensitivity, and selectivity.

This recent technology responds to a major preoccupation of public health giving the possibility of rapid and precise detection of undesirable or toxic substances.

We aim to develop colorimetric biosensor for toxins in water and liquid food matrices, combining plasmonic gold nanoparticles antibody bioconjugates and microfluidic system toward marketable and portable pointe-of-care for smartphone immunosensing.
