“…Hydrodynamic injection ensured bias‐free and repeatable injections, simple instrumentation, and portability and required only minimal alterations during the microchip fabrication process. MCE‐C 4 D was further applied in the analysis of food products for determination of dipeptides (carnosine and anserine) in poultry meat and of inorganic anions (Cl − and F − ) in whiskey samples for authenticity screening . Application of on‐chip ITP with C 4 D was also demonstrated in multichannel networks for determination of amino acids .…”

The publications concerning capacitively coupled contactless conductivity detection for the 2-year period from mid-2016 to mid-2018 are covered in this update to the earlier reviews of the series. Relatively few reports on fundamental investigations or new designs have appeared in the literature in this time interval, but the development of new applications with the detection method has continued strongly. Most often, contactless conductivity measurements have been employed for the detection of inorganic or small organic ions in conventional capillary electrophoresis, less often in microchip electrophoresis. A number of other uses, such as detection in chromatography or the gauging of bubbles in streams have also been reported.

Screening bioactive compounds from natural product and its preparations using capillary electrophoresisBioactive ingredients of natural products can protect human body from harm, as well as prevent and treat disease. Screening bioactive compounds from natural products is attracting particular attention. It is a great challenge to separate and detect the active compounds from complex matrix natural products. CE plays a vital role in screening active compounds because of its unique features such as high-efficiency separation, short-analysis time, minimal sample consumption, and ease to realize automatization etc. Additionally, CE has been developed various modes owing to its abundant advantages in analysis and separation of compounds. The purpose of this work is to review previous developments and applications of CE in screening bioactive compounds derived from natural products from 2007 to 2017. This review does not only summarize the traditional methods of detecting active ingredients but also briefly introduces some novel assays. The trends in the application of CE in active compounds screening are addressed in the article.

Rapid and inexpensive method for the simple fabrication of PDMS‐based electrochemical sensors for detection in microfluidic devices

The fabrication of PDMS microfluidic structures through soft lithography is widely reported. While this well‐established method gives high precision microstructures and has been successfully used for many researchers, it often requires sophisticated instrumentation and expensive materials such as clean room facilities and photoresists. Thus, we present here a simple protocol that allows the rapid molding of simple linear microchannels in PDMS substrates aiming microfluidics‐based applications. It might serve as an alternative to researchers that do not have access to sophisticated facilities such as clean rooms. The method developed here consists on the use of pencil graphite leads as template for the molding of PDMS channels. It yields structures that can be used for several applications, such as housing support for electrochemical sensors or channels for flow devices. Here, the microdevices produced through this protocol were employed for the accommodation of carbon black paste, which was utilized for the first time as amperometric sensor in microchip electrophoresis. This platform was successfully used for the separation and detection of model analytes. Ascorbic acid and iodide were separated within 45 s with peak resolution of 1.2 and sensitivities of 198 and 492 pA/μM, respectively. The background noise was ca. 84 pA. The analytical usefulness of the system developed was successfully tested through the quantification of iodide in commercial pharmaceutical formulations. It demonstrates good efficiency of the microfabrication protocol developed and enables its use for the easy and rapid prototyping of PDMS structures over a low fabrication cost.
