Biosensors and Bioelectronics
The metal-organic frameworks (MOFs) nanozyme-mediated paper-based analytical devices (PADs) have shown great potential in portable visual determination of phenolic compounds in the environment. However, most MOF nanozymes suffer from poor dispersibility and block-like structure, which often prompts deposition and results in diminished enzymatic ...

Chlorpyrifos (CPF) residues in food pose a serious threat to ecosystems and human health. Herein, we propose a three-dimensional folded paper-based microfluidic analysis device (3D-μPAD) based on multifunctional metal-organic frameworks, which can achieve rapid quantitative detection of CPF by fluorescence-colorimetric dual-mode readout.

Cellulose, 2020
Cellulose-based material has been increasingly used as a suitable substrate for depositing metal–organic frameworks (MOFs) in recent years. In this work, MOFs (Cu-BTC) were deposited onto carboxymethylated filter paper (CMP) using four different preparation procedures: one-pot, two-step, layer-by-layer-organic (LbL-org), and layer-by-layer-water ...

Analytical Chemistry
Exploring the high-performance photoelectronic properties of perovskite quantum dots (QDs) is desirable for paper-based photoelectrochemical (PEC) sensing;however, challenges remain in improving their stability and fundamental performance. Herein, a novel Z-scheme heterostructure with host-guest interaction by the confinement of CH3NH3PbBr3 QDs within ...

Separation and Purification Technology, 2019
Abstract In this study, a novel hybrid metal organic framework (MOF) – bucky-paper was developed by seeding crystal growth of Mg-MOF-74 from the surface of carbon nanotube (CNT) mats, called bucky-papers (BP). The seeding density and growth kinetics of the MOF crystals across the CNT-BPs was enhanced through continuous discharge plasma treatments ...
