Silver NPs are substantially more effective than silver ions, enhanced antibacterial properties of silver NPs being demonstrated both in vitro and in vivo.
For these reasons, in this study we investigated the antimicrobial effects of low concentrations of Ag NPs against representative microorganisms of public health concern. Here, we report that different Ag NPs sizes and concentrations can be applied effectively in the control of microorganisms and the prevention of deleterious infections.
Sample preparation is a key step in the analysis process
Parameters for evaporation and their impact on analysis have been discussed
Improvements in matching the sample to the evaporation device characteristics can help reduce variability and improve recovery
Examples for choosing a system based on sample volume, types of analytes, sample load, and initial investment considerations
Automated sample preparation reduces the costs per sample and minimizes sample handling errors. Usually expensive and highly specialized pipetting robots are used. However, most of these systems are not designed with a direct interface for LC-MS applications. In addition common pipetting systems are not optimized for smaller scale sample series. Here we present a new tool for liquid handling of whole blood samples and direct sample injection.READ MORE
