How to measure DNA in urine
Standard DNA detection technique The method of choice for DNA quantification in most laboratories is UV-spectrophotometry. This method is based on the absorption of ultraviolet (UV) light by DNA. Each …
How does it work? A physics model
In this step we explain the relation between the cantilever properties (dimensions, stiffness) and its vibrations. If you need further explanation of physical concepts such as frequency or oscillation I …
The oscillating cantilevers as detecting element
At the University of Twente we have chosen oscillating cantilevers as sensing elements to measure the concentration of VOCs in the exhaled air. A cantilever is a miniature version of …
The artificial nose project
The analysis of your breath can provide much information about processes going on in your body and especially in your lungs. The alcohol breath test is a well-known test, checking …
The cleanroom
When structures become smaller, dust particles, vibrations, water vapor or fatty fumes can easily disturb their fabrication. Therefore, cleanrooms have been developed. In this video Evert Houwman shows what infrastructure …
