Abstract: Disclosed herein are methods and devices for applying two or more mobilization fields in a microchannel using a multifunctional structure and manipulating particles and fluids based on more than one characteristic. Specifically, a fluidic channel comprising at least one metal structure having a coat comprising a conductive material, an insulative material, a semi-conductive material, or a combination thereof, is disclosed. Also disclosed are methods for manipulating or assaying a particle in a sample which comprises subjecting the sample to a fluidic channel comprising at least one metal structure having a coat comprising a conductive material, an insulative material, a semi-conductive material, or a combination thereof and inducing at least one mobilization field such as a magnetic field, an electroosmotic field, an insulative dielectrophoresis (iDEP) field, which iDEP field may be an iDEP trapping field or an iDEP streaming field, or a combination thereof.

Abstract: An apparatus (12) for retaining a shoe (18) within a clothes dryer (10) having a rotatable chamber (16), the apparatus (12) having a shoe tree (28) with a toe support member (38) and a heel support member (36) for maintaining the inner shape of the shoe (18), a bracket (26) interconnecting the shoe tree (28) and a clamp (20) which is releasably secured to the rotatable chamber (16) of the dryer (10).
