Application

Silicone oil has been used:
  • for melting-point and boiling-point apparatus
  • in membrane contactors to impregnate fibers
  • on rheometer samples (chicken skin and bovine gelatin) to prevent evaporation during heating using temperature sweeps and frequency sweeps

Biochem/physiol Actions

Silicone oil is suitable for use in under-oil screenings of proteins.

Features and Benefits

  • High viscosity
  • Low water solubility
  • Low vapor pressure

The in vivo microenvironment of bacterial pathogens is often characterized by nutrient limitation. Consequently, conventional rich in vitro culture conditions used widely to evaluate antibacterial agents are often poorly predictive of in vivo activity, especially for agents targeting metabolic pathways.

We present experiments and theory of a constant flow-driven microfluidic oscillator with widely tunable oscillation periods. This oscillator converts two constant input-flows from a syringe pump into an alternating, periodic output-flow with oscillation periods that can be adjusted to between

We have recently demonstrated strong nuclear deformation of SaOs-2 osteosarcoma cells on poly-L-lactic acid (PLLA) micropillar substrates. In the present study, we first demonstrated that chemical and mechanical properties of the micropillar substrates have no dominant effect on deformation. However
