How does a nanomaterial interact with a cell?


How nanomaterials interact with the environment after they have been disposed of has many implications for potential toxicity and health concerns. Whether nanomaterials are being incorporated into commercial goods for their anti-microbial properties such as in work-out clothes or used for targeted drug therapies their overall prevalence is increasing. Therefore, the likelihood of someone coming into contact with these materials is also increasing.

What does QCM-D have in common with a church bell?

Posted by Jennie Ringberg on December 15, 2015


How does QCM-D work, really? Perhaps you know that a QCM-D sensor is made out of quartz, which is a piezoelectric material. But what does that really mean? And how can that property of the quartz give you information about how much mass you have put on your sensor, or how soft that material on the sensor is?
