abstract = {The development of highly sensitive and selective
biosensors is crucial for early disease, health monitoring,
and treatment. In this study, Zeolitic Imidazolate
Framework-67 (ZIF-67) functionalized with nitrogen-doped
carbon dots (N-CQDs) is designed for the ultra-sensitive and
selective detection of serum albumin in artificial body
fluids. The N-CQD@ZIF-67 (NCZ-67) composite material was
synthesized through a facile and environmental friendly
process, leveraging the unique photoluminescent properties
of nitrogen-doped carbon dots and the robust structural
framework of ZIF-67. The synthesized composite is
characterized using FTIR, PXRD, UV–visible spectroscopy,
photoluminescence spectroscopy, Raman, EDS, XPS, and HRTEM
techniques. It serves as a highly efficient ‘turn-on’
sensor for detecting bovine serum albumin (BSA) with a limit
of detection (LOD) of 0.2129 µM. The sensing mechanism
operates via Förster Resonance Energy Transfer (FRET). The
fluorescent lifetime decay analysis of fluorophore (NCZ-67)
revealed lifetimes of 2.77 μs and 2.11 μs with and without
the analyte BSA, respectively, confirming the FRET
mechanism. The high overlap integral value, 2.61 × 1010
indicates a significantly enhanced FRET efficiency. The
Benesi-Hildebrand equation demonstrates a 1:1 interaction
between the analyte BSA and the NCZ-67 sensor. Additionally,
NCZ-67 shows excellence in detecting albumin in artificial
body fluid samples, confirming the sensor’s
ultra-sensitivity, robustness, selectivity and extending its
applicability in clinical biochemical analysis. The recovery
percentage of BSA in artificial body fluids is around
92–97 $\%$ further validating its potential for clinical
use. The study underscores the potential of N-CQD@ZIF-67 in
developing next-generation biosensors, particularly for the
early detection and monitoring of liver and kidney-related
disorders.},
