UScience Tech Barcelona is a team competing in Sensus 2018, its university is the UVic and UPC. For Sensus 2018, UScience Tech Barcelona investigated the possibilities for creating a biosensor which is able to measure the concentration of [[Vancomycin]].

== Method ==
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 ==
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.
== Cartridge ==
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.
