A sample and practical colorimetric naked-eye chemosensor 3-nitro-4-ethylenediamido-nitrobenzene (2) for metal cations was designed and synthesized.
Thus, efforts should be made to overcome practical barriers related to the newness of green-NM exposure scenarios, the inconsistencies over how to identify and classify NMs, and the questions about metrics for health related-sampling and practical instrumentation [ 117].
Other methods, such as biological testing of fluid or tissue samples, and more practical methods, such as pill counts, more accurately determine whether patients are complying with their recommended medication.
Fluorescence "turn-off" sensors may report false positive results caused by other quenchers in practical samples and are undesirable for practical analytical applications.
Particular attention is given to the requirements to the techniques in terms of precision and throughput, as well as to the issue of availability of samples for analysis and practical solution of this problem.
However, if necessary to achieve the desired sample, and if practical, some items were also checked in real time, immediately after the pharmacist's final check and before they were given to the patient.
The limit of detection is determined as 0.13 nM, the results suggested that as-prepared complex could be a promising material for developing ECL senors to detect the Cd2+ rapidly indwell in environmental and practical samples.
A novel and practical sample pretreatment method based on hollow fiber centrifugal ultrafiltration (HFCF-UF) was developed to determine plasma protein binding by using HPLC.
Fundamental and scientific research for RO membranes based on fine structure analyses by means of transmission electron microscopy with a special technique for sample preparation was conducted, and practical tools for designing new innovative RO membrane were acquired by the structure analyses to quantify the physicochemical and chemical properties of RO membranes.
In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.
