Abstract
In this study, using a thirsty plant extract and a simple hydrothermal method, a nano-probe was introduced to detect the phenobarbital based on fluorescence. Functional groups, particle size, surface morphology, and types of elements were identified using analysis such as FTIR, TEM, SEM, EDX, respectively. The excitation at 355 nm and emission intensity at 446 nm for nano-probe, the nano-probe shows that various parameters such as pH, temperature, and time were investigated for optimization conditions. After optimizing the factors affecting the sensor's response, a linear range between 0 and 750 µM with a detection limit of 5 µM was obtained. Then, the effect of interfering with other materials was investigated and finally, the ability of this sensor to measure the phenobarbital in real samples has been studied.

Abstract
A core element in clinical diagnostics is the data interpretation obtained through the analysis of patient samples. To obtain relevant and reliable information, a methodological approach of sample preparation, separation, and detection is required. Traditionally, these steps are performed independently and stepwise. Microchip capillary electrophoresis (MCE) can provide rapid and high-resolution separation with the capability to integrate a streamlined and complete diagnostic workflow suitable for the point-of-care setting. Whilst standard clinical diagnostics methods normally require hours to days to retrieve specific patient data, MCE can reduce the time to minutes, hastening the delivery of treatment options for the patients. This review covers the advances in MCE for disease detection from 2008 to 2017. Miniaturised diagnostic approaches that required an electrophoretic separation step prior to the detection of the biological samples are reviewed. In the two main sections, the discussion is focused on the technical set-up used to suit MCE for disease detection and on the strategies that have been applied to study various diseases. Throughout these discussions MCE is compared to other techniques to create context of the potential and challenges of MCE. A comprehensive table categorised based on the studied disease using MCE is provided. We also comment on future challenges that remain to be addressed.

Abstract
Neurotoxin (NT), a short-chain α-neurotoxin, is the main neurotoxic protein identified from the venom of Naja naja atra. As an effective drug for the analgesis of advanced cancer patients, NT lasts longer than morphine and does not cause addiction. However, achieving a sensitive and high-resolution measurement of NT is difficult because of the extra-low content of NT in vivo. Therefore, developing a novel method to quantify NT is essential to study its pharmacokinetics in vivo. Although NT contains four primary amine groups that could react with the thiourea in fluorescein isothiocyanate (FITC), we developed a simple and reproducible single-label fluorescent derivatization method for NT which is related to the reaction of N-terminal α-amino of NT alone under optimized derivatization conditions. Furthermore, neurotoxin labelled with fluorescein isothiocyanate (NT-FITC) was prepared by high-performance liquid chromatography (HPLC) with a purity value higher than 99.29% and identified by MALDI-TOF/TOF-MS. Finally, NT-FITC could be detected at 0.8 nmol L(-1) in rat plasma using capillary electrophoresis coupled with laser induced fluorescence detection (CE-LIF). In this paper, the established method robustly and reliably quantified NT labelled with FITC via intravenous and intramuscular administrations in vivo. In addition, this work fully demonstrated the pharmacokinetic characteristics of NT in vivo, which could reduce the risk of drug accumulation, optimize therapies, and provide sufficient evidence for the rational use of NT in clinical and research laboratories.

Abstract
Electrophoretic mobility shift assays (EMSAs) play an important role in analytical chemistry, quantitative bioscience, and point-of-care diagnostics. Emerging microfluidic lab-on-a-chip technologies bring high throughput and multiplexed analysis to affinity-based electrophoretic separations, greatly advancing the performance of traditional EMSAs. This review elaborates on the relevant theoretical basis for EMSAs, surveys microfluidic-based EMSA applications in molecular conformation analyses, immunoassays, affinity assays and genomics, and outlines challenges and potential future improvements needed from this powerful assay.
