Modeling Drop Generation at the Microscale

Hanchak M.S., Furlani E.P., Eastman Kodak Company, US

In this presentation a numerical model is described for predicting drop generation from microscale liquid jets of Newtonian fluid. The model uses a one-dimensional slender-jet approximation to obtain the equations of motion for the free-surface [...]

Particle Transport in Magnetophoretic Microsystems

Furlani E.P., University at Buffalo, US

Magnetophoretic microsystems are finding increasing use in biotechnology and biomedicine for applications such as bioseparation and immuno-assays. These microfluidic systems typically contain embedded elements that produce a magnetic field distribution within a microchannel. This applied [...]

Analysis of an Electrostatically Actuated MEMS Drop Ejector

Furlani E.P., Eastman Kodak Company, US

MEMS are finding increasing use for applications that require the controlled generation and delivery of picoliter-sized droplets. Common applications include biomedical and biochemical microdispensing and most notably, ink jet printing. Micro-droplets can be produced as [...]

Modeling Magnetic Transport of Nanoparticles with Application to Magnetofection

Furlani E.P., Ng K.C., University at Buffalo, US

Magnetic nanoparticles are finding increasing use in a broad range of bioapplications, primarily as carrier particles for biomaterials such as cells, proteins, antigens and DNA. The use of biofunctional magnetic particles enables selective immobilization and [...]

Integrated Thermal Modulation and Deflection of Viscous Microjets with Applications to Continuous Inkjet Printing

Furlani E.P., Ng K.C., Lopez A.G., Anagnostopoulos C., Eastman Kodak, US
