The use of sensors in critical areas for human development such as water, food, and health
has increased in recent decades. When the sensor uses biological recognition, it is known …

In recent years, silver nanoparticles (AgNPs) have been regarded as one of the most
outstanding nanomaterials thanks to the possession of many advantageous properties …

Exploring peroxidase-like nanozymes with high catalytic activity is an urgent task to
construct a fast, convenient, and selective colorimetric sensing platform. In this work, a …

In this paper, copper nanocubes (CuNCs) were grown on top of few-layer and multi-layer
graphene (FLG and MLG) nanomaterial by electrodeposition, to develop a sensitive and …

In this study, a simple, eco-friendly and low-cost approach was used to fabricate silver
nanoparticles (AgNPs) from an aqueous extract of Gleditsia australis (GA) fruit. The …

This article presents the development and application of a green lignin-derived graphene
biosensor for Troponin I, a biomarker for Acute Myocardial Infarction (AMI). The graphene …

We propose here a simple label-free enzymatic-based colorimetric glucose biosensor using
silver triangular nanoplates (AgTNPs) as a multifunctional probe that acts as a signal …

In this study, nitrogen-doped carbon dots (N-CDs) with excellent peroxidase-like activity
were prepared using locust powder as the carbon source by a self-exothermic reaction. The …

The nanomaterials-based artificial enzymes have attracted great attention because of their
high stability, good biocompatibility, high catalytic efficiency, and low cost in recent years …

Infectious diseases pose a serious threat to global health. Although immunizations can
control most viral infections, bacterial infections, particularly those caused by drug-resistant …
