Comments on “A Simple Device for Syringe-to-Syringe Transfer During Lipofilling”

New Device for Obtaining Subcutaneous Tissue Specimens: the Aspirating Syringe.

Electrostatic device for active transfer of submicroliter samples from syringe pipettors.

The electrostatic charger can be operated in automatic or manual mode. In automatic mode, the high voltage is controlled by means of an analog input ranging from 0–5 V, corresponding to 0–20 kV at the high voltage side of the device. In our case, a laptop running NI Labview 7.1® and a DAQCard 6062E® (National Instruments, Austin, TX, USA) was used to provide the analog control signal. The 0–5 V...

Downward movement of syringe pumps reduces syringe output.

We studied how lowering a syringe pump and changing the outflow pressure could affect syringe pump output. We experimentally reduced the height of three different syringe pump systems by 80 cm (adult setting) or 130 cm (neonatal setting), as can happen clinically, using five flow rates. We measured the time of backward flow, no flow and the total time without flow. An exponential negative corre...

A Microliter Syringe Method for Counting Bactcria

During our study of the relationship between propagule size and reproduction capacity of microorganisms on agar media1), it was necessary to determine concentrations of various species of bacteria and actinomycetes. Since bacterial counts made in haemacytometer had been shown to be unreliable because the amount of samples counted was not precise3,4,5) and difficult due to insufficient color con...

Syringe-injectable electronics.

Seamless and minimally invasive three-dimensional interpenetration of electronics within artificial or natural structures could allow for continuous monitoring and manipulation of their properties. Flexible electronics provide a means for conforming electronics to non-planar surfaces, yet targeted delivery of flexible electronics to internal regions remains difficult. Here, we overcome this cha...
