“…This integrated device has been successfully applied for quantifying pyrene and carbofuran in soil, with results comparable with conventional benchtop methods. Recently, Breadmore’s group developed a 3D-printed millifluidic device with an integrated porous structure that separated the sample channel and reagent channel. , Soil mixed with water and reagents could be directly pipetted into the sample channel. The porous structure filtered out soil particles but allowed solutes to diffuse to the reagent channel for detection.…”

Investigating environmental processes, especially those occurring in soils, calls for innovative and multidisciplinary technologies that can provide insights at the microscale. The heterogeneity, opacity, and dynamics make the soil a “black box” where interactions and processes are elusive. Recently, microfluidics has emerged as a powerful research platform and experimental tool which can create artificial soil micromodels, enabling exploring soil processes on a chip. Micro/nanofabricated microfluidic devices can mimic some of the key features of soil with highly controlled physical and chemical microenvironments at the scale of pores, aggregates, and microbes. The combination of various techniques makes microfluidics an integrated approach for observation, reaction, analysis, and characterization. In this review, we systematically summarize the emerging applications of microfluidic soil platforms, from investigating soil interfacial processes and soil microbial processes to soil analysis and high-throughput screening. We highlight how innovative microfluidic devices are used to provide new insights into soil processes, mechanisms, and effects at the microscale, which contribute to an integrated interrogation of the soil systems across different scales. Critical discussions of the practical limitations of microfluidic soil platforms and perspectives of future research directions are summarized. We envisage that microfluidics will represent the technological advances toward microscopic, controllable, and in situ soil research.

“…The contents of Fe 2+ and Fe 3+ ions in gastric and intestinal digests of seal meat described in Section 3.4 (as shown in Figure 5 ) were measured spectrophotometrically [ 34 ]. Samples were first dissolved in distilled water, incubated for 30 min, and centrifuged at 4000 rpm for 1 min.…”

Evaluation of the Preservation and Digestion of Seal Meat Processed with Heating and Antioxidant Seal Meat Hydrolysates

Seal meat is of high nutritive value but is not highly exploited for human food due to ethical issues, undesirable flavors, and loss of nutrients during the processing/cooking step. In this work, commercially available processed seal meat was treated with its hydrolysates as preservatives with the aim of improving nutrient bioavailability. The contents of the nutrients were analyzed after digestion using a simulated dynamic digestion model, and the effects of different processing conditions, i.e., low-temperature processing and storage (25 °C) and high-temperature cooking (100 °C), of seal meat were investigated. Hydrolysates with antioxidant activity decreased the amounts of the less desirable Fe3+ ions in the seal meat digests. After treatment with hydrolysates at room temperature, a much higher total Fe content of 781.99 mg/kg was observed compared to other treatment conditions. The release of amino acids increased with temperature and was 520.54 mg/g for the hydrolysate-treated sample versus 413.12 mg/g for the control seal meat sample treated in buffer. Overall, this study provides useful data on the potential use of seal meat as a food product with high nutritive value and seal meat hydrolysates with antioxidant activity as preservatives to control oxidation in food.

“…This method has been commercialized along with a wide range of proprietary photopolymer-based inks, which are typically crosslinked via controlled optical irradiations. 28 Depending on the number of printing heads that can be simultaneously operated, Polyjet printing and Multijet modelling are the most common methods of material jetting. The unique aspect of PolyJet printing lies in the compactly assembled printing nozzles that are synchronized to deliver a heterogeneous material system including supporting and multiple building inks (Fig.…”
