Recently, inkjet-printing has gained increased popularity in applications such as flexible electronics and disposable sensors, as well as in wearable sensors because of its multifarious advantages. This work presents a novel, low-cost immobilization technique using inkjet-printing for the development of an aptamer-based biosensor for the detection of lysozyme, an important biomarker in various ...

The condition of cells in Pseudomonas aeruginosa biofilms was monitored via the electrochemical detection of the electro-active virulence factor pyocyanin in a fabricated microfluidic growth chamber coupled with a disposable three electrode cell. Cells were exposed to 4, 16, and 100 mg L(-1) colistin sulfate after overnight growth. At the end of testing, the measured maximum peak current (and t...

BACKGROUND Few studies have investigated the difference in bacterial contamination between conventional reused ventilator systems and disposable closed ventilator-suction systems. The aim of this study was to investigate the bacterial contamination rates of the reused and disposable ventilator systems, and the association between system disconnection and bacterial contamination of ventilator sy...

Electrochemical detection of metal cations at paper-based sensors has been suggested as an attractive alternative to current spectroscopic and chromatographic techniques due the ease fabrication, disposable nature, low cost. Herein, a novel carbon black (CB), dimethylglyoxime (DMG) ink is designed electrode modifier in conjunction with 3-electrode inkjet-printed paper substrates for use adsorpt...

One of the biggest global public health issues, cancer has a negative impact on people's and quality life. Therefore, it is undeniable that interest in drugs for treatment increased. On other hand, addition to patient safety during administration used due their possible toxic properties, crucial maintain safe working environment safeguard professionals who provide from possibility coming into t...

Creatinine is the final metabolic product of creatine in muscles and a widely accepted biomarker for chronic kidney disease. In this work, we present non-enzymatic sensor based on an electrochemical pretreated screen-printed carbon electrode (PTSPCE) with electrodeposited Cu nanoparticles (CuNPs). To function PoC format, prepared PTSPCE/CuNPs sensors were used as disposable elements portable po...
