Dielectrophoretic Force Equilibrium of Complex Particles
(American Physical Society, 2020)
In contrast to the commonly used spherical Janus particles, here we use engineered Janus particles that are fabricated by means of the photolithography technique for precise control over their geometry and coated regions. ...

Post-quantum biometric authentication based on homomorphic encryption and classic McEliece
(MDPI, 2023-01)
Homomorphic encryption is a powerful mechanism that allows sensitive data, such as biometric data, to be compared in a protected way, revealing only the comparison result when the private key is known. This is very useful ...

Wall Repulsion during Electrophoresis: Testing the Theory of Concentration-Polarization Electroosmosis
(AIP Publishing, 2023)
We experimentally study the repulsion of charged microscopic particles with the channel walls during electrophoresis in microfluidic devices. For low frequencies of the electric fields (< 10 kHz), this repulsion is mainly ...
