Pumping of mammalian cells with a nozzle-diffuser micropump.
We discuss the successful transport of jurkat cells and 5D10 hybridoma cells using a reciprocating micropump with nozzle-diffuser elements. The effect of the pumping action on cell viability and proliferation, as well as on the damaging of cellular membranes is quantified using four types of well-established biological tests: a trypan blue solution, the tetrazolium salt WST-1 reagent, the LDH c...
متن کاملOptical Pumping
T he rather odd term optical pumping means just what it says. In general “pumping” is a process of raising matter from lower to higher energy; for example, raising the potential energy of water hy moving it from an underground well to an elevated tank. In this article we shall he concerned w i t h the pumping of individual atoms from lower to higher states of internal energy. The word optical r...
متن کاملOptical Pumping
Optical pumping uses light to affect the internal degrees of freedom of a sample of atoms in a vapor. These internal degrees of freedom are angular momentum states of the atomic ground state, which are populated when light is absorbed and emitted. This experiment reveals many phenomena of quantum mechanics including angular momentum selection rules, the density matrix, and resonance. Optical pu...
متن کاملPumping iron
The primary role of the ZIP13 metal transporter in flies is to move iron ions out of cells, rather than moving zinc ions into cells, as is the case in human cells.
متن کاملPumping in an interacting quantum wire
We study charge and spin pumping in an interacting one-dimensional wire. We show that a spatially periodic potential modulated in space and time acts as a quantum pump, inducing a dc–current component at zero bias. The current generated by the pump is strongly affected by the interactions. It has a power-law dependence on the frequency or temperature, with the exponent determined by the interac...
