Self-Mixing Laser Distance-Sensor Enhanced by Multiple Modulation Waveforms
Sensors, 2022 Optical rangefinders based on Self-Mixing Interferometry are widely described in literature, but not yet on the market as commercial instruments. The main reason is that it is relatively easy to propose new elaboration techniques and get results in ...

Click Capture SELEX for the Identification of Click-Modified Aptamers Targeting Small Molecules in Solution. [PDF]
ChemistryUsing kanamycin A as a model target, we developed click‐capture SELEX to identify nucleobase‐modified aptamers capable of binding small molecules in solution. This approach enables flexible incorporation of nucleobase modifications via CuAAC, allowing the chemical properties of the aptamer to be tailored to the target molecule.
