We usually think that doctors are behind medical discoveries but what about all the engineers developing methods and devices to improve our health? Let's share a beer and explore health at the nanoscale!
Are there nanoplastics in your personal care products?
Laura Hernandez (PhD Candidate - Chemical engineering department at McGill University)
Fragmentation of plastic debris and the commercial use of plastic microbeads have led to the widespread distribution of microplastics in natural environments. Microbeads used in consumer products such as scrubs and shampoos are processed by mechanical means that may lead to their fragmentation into potentially more hazardous nanoplastics. In this study, three commercial facial scrubs containing polyethylene microbeads were examined to verify whether they contained nanoplastics. This study confirms the (unexpected) presence of nanoplastics in personal care products containing polyethylene micro
Shrinking the lab for cancer and synthetic biology
Professor Steve Shih (Professor - Electrical and Computer Engineering department at Concordia University)
Remember the days of when you used beakers and flasks during a chemistry experiment? These days are long gone and a new revolution has come to town – namely ‘lab-on-a-chip’ or microfluidics. Lab-on-chip is a miniaturized laboratory that will fit on the palm of your hand which is a novel way on solving some of the most pressing scientific problems of today. In this talk, I will describe some of these ‘lab-on-chip tools and describe how we use these tools for two different applications: 1) to solve cancer challenges and 2) how to engineer organisms for producing valuable products.
