Visualization of flagellar interactions on bacterial carpets.
Methods for the in-depth study of the physics of microscale actuation of microfluidics environments by flagellated bacteria 'teamsters' have been developed. These methods, which include single and multi-colour fluorescent labelling and electron microscopy allow for the analysis of the effect that individual flagellar filaments have on bacterially driven microstructures, and allow for the invest...
متن کاملFlow Induced by Bacterial Carpets and Transport of Microscale Loads
Microfluidics devices carry very small volumes of liquid though channels and have been used in many biological applications including drug discovery and development. In many microfluidic experiments, it would be useful to mix the fluid within the chamber. However, the traditional methods of mixing and pumping at large length scales don't work at small length scales. Recent experimental work has...
متن کاملQuantum carpets, carpets of light
In 1836 Henry Fox Talbot, an inventor of photography, published the results of some experiments in optics that he had previously demonstrated at a British Association meeting in Bristol. "It was very curious to observe that though the grating was greatly out of the focus of the lens...the appearance of the bands was perfectly distinct and well defined...the experiments are communicated in the h...
متن کاملUse of Bacterial Carpets to Enhance Mixing in Microfluidic Systems
We demonstrate that flagellated bacteria can be utilized in surface arrays (carpets) to achieve mixing in a low-Reynolds number fluidic environment. The mixing performance of the system is quantified by measuring the diffusion of small tracer particles. We show that the mixing performance responds to modifications to the chemical and thermal environment of the system, which affects the metaboli...
متن کاملCEREBROSPINAL FLUID FINDINGS IN NEONATAL BACTERIAL MENINGITIS
Background : Meningitis is more common during the neonatal period than other periods of life and has a prevalence of one in 1000 live births. The similarity of its clinical manifestations with other infectious diseases makes it difficult to diagnose. The aim of the current study was to determine the relationship between age, sex, clinical signs and symptoms and laboratory test results of ne...
