Microsensors

How Surflay Microsensors work (Flyer) |
How Bioanalysis via Microparticles work - WhisperSense Platform (External link) |

Surflay's microsensors are modified microparticles, which can quantify various parameters such as:

  • pH
  • temperature
  • O2 amount
  • chloride amount
  • glucose amount
  • biomolecular interactions (via WhisperSense platform)

No electronic part must be in contact with the sample: changes in microparticle's fluorescence intensity are used for analysis. These microsensors are therefore ideal for measurements in smallest spaces:

  • microfluidics
  • cell cultures
  • cell arrays
  • organ-on-a-chip and more

 

There are three approaches to use microsensors i.e. dye-embedded microparticles:

  • Fluorescence lifetime measurements are independent of the concentration and size of the size
  • Intensity-based measurements require internal fluorescence standards or dual fluorescence in order to eliminate the influence of particle size and sample transparency. 
  • Whispering Gallery Modes (only for bioanalysis)

In the image, for example, it can be seen that the fluorescence of pH microsensors change with pH.
