The recent maturation of continuous-flow microfluidic technologies has coincided with transformative new methods to profile single cells, including their genetic types, protein expression and enzyme activities. Continuous-flow high-throughput single-cell screening and sorting can reveal relationships across cellular phenotypes (e.g., enzyme activity and secretion) and genetic fingerprints. This technology provides unique opportunities, as well as experimental and computational challenges, for integrative approaches that can process large amounts of single-cell data. In this chapter, we discuss recent advances in integrated continuous-flow microfluidic approaches with a focus on measurements and statistical analysis of single-cell enzyme activity and their applications in quantitative biology, synthetic biology, and diagnosis.

Self-assembled bottlebrush block copolymers (BBCPs) offer a vibrant, eco-friendly alternative to traditional toxic pigments and dyes, providing vivid structural colors with significantly reduced environmental impact. Scaling up the synthesis of these polymers for practical applications has been challenging with conventional batch methods, which suffer from slow mass and heat transfer, inadequate mixing, and issues with reproducibility. Precise control over molecular weight and dispersity remains a significant challenge for achieving finely tuned color appearances.

By integrating ultraviolet (UV) photocatalytic oxidation digestion with segmented continuous flow analysis technology, an online measurement method and analysis system for the alkaline chemical oxygen demand (COD) in seawater, based on the color-change reaction of potassium permanganate, has been established. This represents the first application of UV photocatalytic oxidation technology in the measurement of COD in seawater. The system effectively overcomes the limitations of high-temperature and high-pressure digestion methods employed in traditional COD analysis.

The cyclic triangular complex - silver (I) 4-nitro-3,5-bis(trifluoromethyl)pyrazolate (Agpz) with super π-acidity shows great potential in adsorptive desulfurization (ADS) as a novel adsorbent, however, it fails to work well in the continue flow adsorption study. In order to improve its dynamic adsorption performance, a composite has been prepared by mixing Agpz and multilayer graphene (MG) in methanol. Based on the results of characterization by FT-IR, XPS, SEM, and so on, the optimal mass ratio of Agpz:MG in the synthesis is 0.

This study rigorously evaluates the adsorption performance of the Cry-Ca-COS monolith for phosphate removal in a column operation mode. Characterization of the material both before and after exhaustion in a continuous flow system (column form) showed no difference compared to results from a batch system (tablet form). The XPS results indicated that the adsorption mechanism of phosphate on the Cry-Ca-COS column involved surface microprecipitation and ligand exchange (inner-sphere complexation).
