Team Sandbox 2018

Team Sandbox is a team competing in Sensus 2018, its university is the TU Eindhoven. For Sensus 2018, Team Sandbox investigated the possibilities for creating a biosensor which is able to measure the concentration of Vancomycin. The full TRD can be found via this link


Spectrophotometry (Light absorbtion). Vanomycin has the property that it absorbs photons of a specific wavelength, the strength of the absorbtion is the dependant on the concentration. By looking at the transmission for a specific wavelenght of light the concentration of Vanomycin can be determined.

Molecular Recognition

The detection method is based on the absorbance properties that vancomycin possesses.

Physical Transduction

UV light (280 nm) was immited on a quartz cuvette. The light that is not absorbed passes through an optical filter (bandpass filter with center wavelength 300 nm) which then falls on a sicilone detector.


To plasma spiked with vancomycin, trichloroacetic acid (TCA) is added. The mixture is then centrifuged at 15000 rpm for 3 mins to separated proteins from plasma. Then, the supernatant is seperated from the precipitated proteins, and diluted to 1:10 volume ratio.
