Abstract
The artificial photosynthesis efficiency is restricted for the covering of introduced light-absorbing antennas, where they could generally be immobilized at specific surface sites of semiconductors. Here, we highlight the emerging π-π interaction strategies in realizing overall surfacial antenna immobilization onto semiconductor supports, during which large-scale built-in electric fields are established, strongly driving photocarrier migration to catalytic centers accompanied with enhanced light absorption. By taking porphyrin and ZIF-8 as a prototype, both theoretical calculation and experimental results show that the photocatalytic systems with overall surfacial antennas could absorb broader visible light and form abundant photocarrier transport pathways from porphyrin to ZIF-8, boosting the generation of superoxide and organic synthesis efficiency. This work develops a universal strategy for design of efficient artificial photosynthetic systems.

Abstract
Screen-printed electrodes (SPEs) coupled with flow systems have been reported in recent decades for an ever-growing number of applications in modern electroanalysis, aiming for portable methodologies. The information acquired through this combination can be attractive for future users with basic knowledge, especially due to the increased measurement throughput, reduction in reagent consumption and minimal waste generation. The trends and possibilities of this set rely on the synergistic behavior that maximizes both SPE and flow analyses characteristics, allowing mass production and automation. This overview addresses an in-depth update about the scope of samples, target analytes, and analytical throughput (injections per hour, limits of detection, linear range, etc.) obtained by coupling injection techniques (FIA, SIA, and BIA) with SPE-based electrochemical detection.
