introduction: erythrocyte sedimentation rate (esr) remains as one of the most reliable tests in clinical practices. yet its use is time consuming and requires a large blood sample. the aim of this study was assessing a faster and reliable method of esr estimation. methods: an esr estimation method was described and performed on 108 patients using capillary tube (micro esr) and capillary periphe...

A modified capillary-growth method is described that has substantial advantages for standard and high-throughput protein crystal growth. Protein-containing drops are injected into vapor-permeable flexible X-ray-transparent polyester tubing. The protein concentration in the drop increases over time by water transport through the tubing wall at a rate controlled by the wall thickness and ambient ...

We report an improved interface for two-dimensional capillary electrophoresis. This interface is based on capillary tubing and a Plexiglas chip, both of which were milled using a micro-dicing saw. The interface was evaluated and compared to a traditional interface design for both pseudo one-dimensional and two-dimensional capillary electrophoresis. We observe less than 70% transfer efficiency f...

We present a conceptually new approach for the detection of magnetic objects flowing through a fluidic channel. We produce an elastic and stretchable magnetic sensor and wrap it around capillary tubing. Thus, the stray fields induced by the flowing magnetic objects can be detected virtually in all directions (isotropic sensitivity), which is unique for elastic sensors when compared to their rig...

In recent years, there is a surge in the popularity of using insulin pump or continuous subcutaneous insulin infusion (CSII) therapy, as opposed to multiple daily injections (MDI) by insulin syringe or an insulin pen. Some case studies have suggested that insulin delivery failure may be caused by the precipitation of insulin within the infusion set. Speculation also exists that the flow of insu...

A miniaturized frit inlet asymmetrical flow field-flow fractionation (mFI-AFlFFF) channel has been constructed and tested for the separation of proteins. By scaling down the geometrical channel dimension of a conventional FI-AFlFFF system, flow rate ranges that can be manipulated were decreased to 20-30 microL/min, which reduces the injection amount of sample materials. The end effect contribut...

A simple, low-cost and on-demand microfluidic controlling platform was developed based on a capillary-tuned solenoid microvalve suction effect without any outer pressure source. The suction effect was employed as a stable driving force for manipulating micro-fluid by connecting a piece of capillary tubing between the microvalve and the chip. The suction volume could be controlled from microlite...

A hollow-cathode microplasma modified the lumenal surface of small-diameter polyethylene (PE) tubing. A microwave cavity diagnostic was used to measure the density of the microplasma. Plasma light output was observed with a monochromator at various positions along the PE tube to assess uniformity. Treatment effectiveness was evaluated by measuring the variation in capillary rise at various posi...
