“…Besides, the effects of the nonionic surfactant Pluronic F-127 and the close distance between nanobeads on the zeta potential could have an impact on the electrokinetic phenomenon, including the stability of particle dispersion and electrophoretic mobility. The nonionic surfactant on the surface of the particles induced a decrease in the zeta potential 28,29) and a slight shift of the slipping plane, 30) and facing particle surfaces close to the Debye layer change the shape of the potential distribution. 31) These effects of the electrokinetic potential on electrophoretic mobility are important for understanding the electrophoretic force on the nanobeads when the EB was irradiated to disperse the nanobeads.…”

A reversible concentration of nanoparticles in water solution is produced on a nanopore fabricated in situ by inverted-electron beam lithography (I-EBL) in a SiN membrane. The SiN membrane separated the water solution and a vacuum chamber of the EB system. The nanopore led to a small leakage of water that flowed to the vacuum chamber. This flow led to the collection of the nanoparticles within an area of less than 3 µm surrounding the nanopore. Then, the EB-induced Coulomb force rapidly released the nanoparticles from only the targeted nanopore. This electron beam direct manipulation of the nanoparticles can provide simple in situ microfluidics in analytical methods for biochemistry.
