“…62 The most common method for the synthesis of metal NPs using microfluidics is the chemical reduction method, in which a reducing agent and a metal salt solution are injected into a microfluidic chip to fully react. 63 During the whole reaction process, the reaction conditions, including the temperature, flow rates, and other parameters affect the morphology and size of the final product, 64 so the design of the microfluidic chip occupies an important position. A commonly used chip design is the serpentine channel, which can enhance the mixing between reagents.…”

Optical biosensors are platforms that translate biological information into detectable optical signals, and have extensive applications in various fields due to their characteristics of high sensitivity, high specificity, dynamic sensing, etc. The development of optical sensing materials is an important part of optical sensors. In this review, we emphasize the role of microfluidic technology in the preparation of optical sensing materials and the application of the derived optical sensors in the biomedical field. We first present some common optical sensing mechanisms and the functional responsive materials involved. Then, we describe the preparation of these sensing materials by microfluidics. Afterward, we enumerate the biomedical applications of these optical materials as biosensors in disease diagnosis, drug evaluation, and organ‐on‐a‐chip. Finally, we discuss the challenges and prospects in this field.

“…Spherical silver nanoparticles with a mean diameter of 7.6 ± 1.8 nm were successfully obtained in a droplet flow microfluidic device using AgNO 3 as precursor, NaBH 4 as reducing agent, EDTA as complexant and PVP as dispersant (Table 3) [99]. The spherical-shaped Ag nanoparticles with an average size of 4 nm and Au nanoparticles with an average size of 14-17 nm could be obtained in a segmented flow capillary microreactor using AgNO 3 and AuHCl 4 •3H 2 O as the respective metal precursors, silicon oil as continuous phase, NaBH 4 and sodium citrate as reducing agent [100].…”

Heterogeneous catalysis plays a central role in the chemical and energy fields, owing to the high and tunable activities of solid catalysts that are essential to achieve the favorable reaction process efficiency, and their ease of recycle and reuse. Numerous research efforts have been focused on the synthesis of solid catalysts towards obtaining the desired structure, property and catalytic performance. The emergence and development of microfluidic reactor technology provide a new and attractive platform for the controllable synthesis of solid catalysts, primarily because of its superior mixing performance and high heat/mass transfer efficiency. In this review, the recent research progress on the synthesis of solid catalysts based on microfluidic reactor technology is summarized. The first section deals with the synthesis strategies for solid catalysts, including conventional methods in batch reactors and microfluidic alternatives (based on single- and two-phase flow processing). Then, different kinds of solid catalysts synthesized in microflow are discussed, especially with regard to the catalyst type, synthetic process, structure and property, and catalytic performance. Finally, challenges in the microreactor operation and scale-up, as well as future perspectives in terms of the synthesis of more types of catalysts, catalyst performance improvement, and the combination of catalyst synthesis process and catalytic reaction in microreactors, are provided.
