During the past few decades, there has been a growing trend towards the use of
smartphone-based analysis systems. This is mainly due to its ubiquity, its increasing …

Single atom catalysts (SACs) have emerged as a promising catalyst material architecture for
energy, chemical, and environmental applications. In the past several years, SACs have …

This review is focused on the analysis of recent developments in the application of polymers
in the detection and quantification of target species. The work begins with a description of …

Water pollution from industrial or household waste, containing dyes from the textile industry,
poses a significant environmental challenge requiring immediate attention. In this study, we …

We have developed an in situ methodology for determining nitrite concentration in
processed meats that can also be used by unskilled personnel. It is based on a colorimetric …

An inexpensive hand-held device for analysis of colorimetric sensor arrays (CSAs) has been
developed. The device makes use of a contact image sensor (CIS), technology commonly …

We have prepared high-performance functional aromatic polyamides with sensory pendant
groups toward amines. These polymers are colourless. The pendant groups have …

In this work, we report the design, the development and the characterization of the analytical
performances of a colorimetric smartphone-based immunosensor for the detection of cancer …

It is challenging to develop a robust nanoprobe for real-time operational and accurate
detection of heavy metals in single cells. Fe-CN coordination chemistry has been well …
