Both assay types have similar characteristics for the determination of estrogen in sewage and urine samples e.g. 6 25 h assay period with detection and determination limits and EC50 values for 17β-estradiol of 2.8 ng L− 1, 5.9 ng L− 1, 33.2 ng L− 1 (nAES-P) and 3.1 ng L− 1, 6.7 ng L− 1 and 39.4 ng L− 1 (nAES-T).
The proposed sensors display useful analytical characteristics for the determination of ROX in bulk powder and its pharmaceutical formulation.
The FDH Aucoll Cyst AuE biosensor exhibited rapid and sensitive response to fructose, allowing the obtention of improved analytical characteristics for the determination of fructose with respect to other FDH electrochemical biosensors.
The zeta potential (ZP) measurements, which are one of the most important characteristics for the determination of stability, were performed in a pH range from 3 to 8 (Fig. 2).
Consequently, it remains a great challenge to fabricate simple, low-cost, stable, sensitive, and selective CMEs that can improve the characteristics of electrocatalytic activity for determination of CySH.
As a result, it is necessary to have further efforts to fabricate simple, low cost, stable, sensitive and selective CMEs that can improve the characteristics of electrocatalytic activity for determination of CySH.
Receiver operating characteristics analysis was used for determination of an optimal cut-off level for APC in differentiating cases from controls.
Details regarding sampling strategies and assay characteristics for the laboratory determinations of the other serum markers have been described previously [ 7, 11].
Information was collected on the publication year, study period, setting, design, number of participants, selection and characteristics of participants, laboratory methods for determination of VRE infection status, characteristics and timing of interventions, duration of follow-up, timing and frequency of outcome measurements, and the reporting of other possible confounding variables.
The application of silicalite for improvement of working characteristics of conductometric enzyme biosensors for determination of sucrose was studied in this research.
