Office Paper and Laser Printing: A Versatile and Affordable Approach for Fabricating Paper-Based Analytical Devices with Multimodal Detection Capabilities

TL;DR: The study explores the treatment of a multi-metal waste using biopolymer cryogels for enhanced adsorption of valuable metals. The process involves flocculation, precipitation, and adsorption. The spent adsorbents can be pyrolyzed to reduce electrical resistance.

TL;DR: Researchers develop wax chalk and self-heating paper-based analytical devices (SH PADs) for detecting Bisphenol A (BPA), a toxic and carcinogenic xenoestrogen, with potential applications in environmental monitoring and public health risk assessment.

TL;DR: This review highlights recent applications of μPADs for environmental analysis along with technical advances that may enable μPads to be more widely implemented in field testing.

TL;DR: How the field of electrochemical paper-based analytical devices (ePADs) has grown since it was introduced a decade ago is reviewed and how the current ePAD technologies have progressed to meet the analytical and practical specifications required for field and/or POC applications are discussed.

TL;DR: In this article, the paper surface was oxidized to promote the conversion of hydroxyl into aldehyde groups, which were then chemically activated for covalent coupling of enzymes.

TL;DR: Recently reported microfluidic paper-based analytical devices that incorporate different detection methods such as colorimetric, electrochemical, fluorescence, chemiluminescence, and electrochemilumineinescence techniques for food and water analysis are reviewed.
