Latest Patents

Nejadnik holds a patent titled "Modification of a flow cell to measure adsorption kinetics under stagnation point flow and development of a setup correction procedure for obtaining adsorption kinetics at the stagnation point." This patent describes a flow cell designed to perform experiments under well-controlled hydrodynamic conditions. The resulting cell combines the advantages of in-situ spectroscopic ellipsometry with stagnation point flow conditions. An additional benefit of the proposed cell is the fixed position of the 'inlet conduit' relative to the substrate, which facilitates the alignment of multiple substrates. Theoretical calculations were conducted using computational fluid dynamics and were compared with experimental data on adsorption kinetics obtained for the adsorption of polyethylene glycol to silica under various experimental conditions. Furthermore, a simple methodology to correct experimental data for errors associated with the size of the measured spot and variations in mass transfer near the stagnation point is introduced. This correction method allows researchers to reasonably estimate adsorption kinetics at the stagnation point and quantitatively compare results across different experimental setups. The applicability of the proposed correction function was verified by evaluating the kinetics of protein adsorption under different experimental conditions.
