Summary: Covalent organic frameworks (COFs) have attracted much attention for their unique physical-chemical characteristics and potential applications in biosensing. In this study, spherical COFs with regular shape and good dispersion were synthesized, and a novel nanoprobe was developed by modifying Histostar on the COFs surface. The nanoprobe was then applied to fabricate an electrochemical biosensor for exosomes detection, achieving a low detection limit and wide linear detection range. This work offers a promising platform for ultrasensitive detection of exosomes.

Summary: In this study, a new adsorbent was developed by functionalizing PAN fiber with F-PEI to efficiently and selectively remove PFOS from firefighting wastewaters. The adsorbent with perfluoroalkyl chains showed shortened adsorption time, improved adsorption capacity with lower pH and higher F-PEI content, and effective suppression of adverse effects from different surfactants and solvents. The adsorbent could meet the EPA standard with residual PFOS concentration below 10 ng/L and be regenerated for multiple uses without significant loss of capacity.

Summary: A simple and robust template-free solvothermal strategy is reported to obtain azobenzene-dangled COFs. The crystallinity, specific surface area, and morphology of Azo-COFs can be controlled by changing the ratio of amine to aldehyde monomers. The reversible trans-to-cis isomerization of the dangled azobenzene units inside the pores allows for intelligent regulation of surface wettability and enhanced adsorption capacity.
