IntroductionAs a 2D material, graphene oxide (GO) is a lattice-like nanostructure of hexagonal carbon rings disrupted by oxygen-containing moieties. In 2012, we discussed the outstanding physicochemical properties offered by GO and how these features can be exploited in unprecedented optical biosensing systems. [1] In fact, GO can be processed in suspension, easily complexed with biomolecules, and offers a universal highly efficient long-range photoluminescence quenching agent-among other functional properties. Furthermore, we highlighted that GO photoluminescences with energy transfer donor/acceptor molecules exposed A few years ago, crucial graphene oxide (GO) features such as the carbon/oxygen ratio, number of layers, and lateral size were scarcely investigated and, thus, their impact on the overall optical biosensing performance was almost unknown. Nowadays valuable insights about these features are well documented in the literature, whereas others remain controversial. Moreover, most of the biosensing systems based on GO were amenable to operating as colloidal suspensions. Currently, the literature reports conceptually new approaches obviating the need of GO colloidal suspensions, enabling the integration of GO onto a solid phase and leading to their application in new biosensing devices. Furthermore, most GO-based biosensing devices exploit photoluminescent signals. However, further progress is also achieved in powerful label-free optical techniques exploiting GO in biosensing, particularly using optical fibers, surface plasmon resonance, and surface enhanced Raman scattering. Herein, a critical overview on these topics is offered, highlighting the key role of the physicochemical properties of GO. New challenges and opportunities in this exciting field are also highlighted.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adma.201805043.in a planar surface. [1] However, GO properties can be tailored according to its oxidation degree, lateral size, and number of layers, which was something little explored 6 years ago, and thus their impact on the overall biosensing performance was almost unknown. In addition, most of the biosensing systems based on GO were amenable to working as colloidal suspensions. Though, recent literature reports conceptually new approaches obviating the need of colloidal suspensions, which facilitates integration of GO-based biosensors into the solid phase and allows for their applications in new devices. Furthermore, the majority of the GO-based optical biosensing techniques rely on photoluminescent signals. However, further progress has also been achieved in powerful label-free optical techniques exploiting GO in biosensing. Here, we introduce a progress report on this exciting topic, underscoring challenges and opportunities in (bio)sensing accordingly.

Digital PCR (dPCR) surpasses the performance of earlier PCR formats because of highly precise, absolute quantification and other unique merits. A simple thermocycling approach and durable microcarrier are of great value for dPCR advancement and application. Herein, a near‐infrared (NIR) controlled thermocycling approach by embedding magnetic graphene oxide (GO) composite into the agarose microcarriers is developed. The core‐shell composite is constructed by sequentially encapsulating GO and silica outside the magnetic nanocores. Benefiting from these additives, the resultant composite agarose gains appealing features as light‐driven temperature changing, switchable gel–sol phase transforming, biocompatibility, and magnetic traction. By further emulsifying into droplets via the microfluidics method, the influence of typical parameters including material loading amount, laser intensity, and droplet diameter at various ranges is investigated for assembling microcarriers with different responsiveness. Then a paradigm of the NIR program can be easily tailored for PCR thermocycling. Finally, the feasibility of the approach is verified by detecting statistically diluted Klebsiella pneumoniae DNA samples, from 0.1 to 2 copies per drop. It is anticipated that this method has promising prospects for dPCR‐based and other temperature‐controlled applications.

Optical sensors for determination of biogenic amines in food

This review presents the state-of-the-art of optical sensors for determination of biogenic amines (BAs) in food by publications covering about the last 10 years. Interest in the development of rapid and preferably on-site methods for quantification of BAs is based on their important role in implementation and regulation of various physiological processes. At the same time, BAs can develop in different kinds of food by fermentation processes or microbial activity or arise due to contamination, which induces toxicological risks and food poisoning and causes serious health issues. Therefore, various optical chemosensor systems have been devised that are easy to assemble and fast responding and low-cost analytical tools. If amenable to on-site analysis, they are an attractive alternative to existing instrumental analytical methods used for BA determination in food. Hence, also portable sensor systems or dipstick sensors are described based on various probes that typically enable signal readouts such as photometry, reflectometry, luminescence, surface-enhanced Raman spectroscopy, or ellipsometry. The quantification of BAs in real food samples and the design of the sensors are highlighted and the analytical figures of merit are compared. Future instrumental trends for BA sensing point to the use of cell phone-based fully automated optical evaluation and devices that could even comprise microfluidic micro total analysis systems.
