Oxidative stress, resulting from an imbalance between reactive oxygen species (ROS) and antioxidants, is a critical factor in the pathogenesis of a wide range of diseases. The excessive accumulation of ROS can cause severe cellular damage, leading to tissue dysfunction and disease progression. The development of nanomaterials with antioxidant properties presents a promising strategy for addressing this challenge. Herein, we report the fabrication of albumin-biomineralized copper nanoclusters (BCNCs) as a novel antioxidant platform and evaluate their effectiveness in combating oxidative stress. Our results show that BCNCs exhibit potent ROS scavenging abilities and protect cells from oxidative stress-induced damage, highlighting their potential as an effective therapeutic strategy for oxidative stress-related diseases.

Abnormal alkaline phosphatase (ALP) levels in the human body are closely associated with various diseases, particularly hepatobiliary diseases and bone diseases. Herein, we constructed a ratiometric sensor based on Förster resonance energy transfer (FRET) using strongly photoluminescent copper nanoclusters (Cu NCs) for the detection of ALP with high sensitivity and specificity. The cysteine-stabilized Cu NCs (Cys-Cu NCs) were synthesized through a ligand-exchange reaction and core-size etching focusing, which displayed bright photoluminescence (PL) with a quantum yield (QY) of 10.

In order to realize efficient detection of Congo red, fluorescence analytical method were adopted and investigated systematically. Based on the superior properties of papain and excellent performance of copper nanoclusters, papain stabilized copper nanoclusters (Cu NCs@PP) with blue fluorescence were rapidly synthesized via a one-pot method. The spherical Cu NCs@PP uniformly dispersed with an average size of about 2.

This study introduces a fluorescence turn-on sensor for the selective detection of valine, an amino acid increasingly recognized as a potential biomarker in cancer diagnostics, using iron(III) (Fe) quenched L-cysteine capped copper nanoclusters (L-cys@CuNCs) based on the paramagnetic quenching mechanism of Fe. The L-cys@CuNCs, synthesized through a one-pot hydrothermal method, exhibit stable green fluorescence, high photostability and a detection limit of 3.00 µM for valine.

Ligand-protected copper nanoclusters (Cu NCs) with atomic precision have emerged rapidly due to their fascinating structural architectures and versatile catalytic properties, making them ideal for investigating structure-activity relationships. Despite their potential, challenges such as stability issues and limited structural diversity have restricted deeper exploration. In this study, three distinct Cu NCs are synthesized using a one-pot reduction strategy by carefully modifying reaction conditions.
