Photothermal-enhanced peroxidase-like activity of CDs/PBNPs for the detection of Fe3+ and cholesterol in serum samples

Nanoparticles Based on Prussian Blue for Biosensor Applications: A Review

“…(A) CD/PBNP photothermal-colorimetric dual-mode detection of Fe 3+ and free cholesterol. Reprinted with permission from ref . Copyright 2021, Springer-Verlag GmbH.…”

“…Dual-mode detection using fluorescence and colorimetric methods can prevent early disease. Song et al 84 prepared CD/PBNPs with fluorescence properties and POD-like activity and successfully detected Fe 3+ and free cholesterol. The imbalance of Fe 3+ and cholesterol in the human body can cause Alzheimer's disease, 162 anemia, hemochromatosis, hypertension, stroke, and other problems.…”

Sensitive Dual-Signal ELISA Based on Specific Phage-Displayed Double Peptide Probes with Internal Filtering Effect to Assay Monkeypox Virus Antigen

“…Synthesis of Fluorescent CPDs. The preparation of CPDs is referred to the literature 47 with modification. Briefly, 270 mg of citric acid and 90 mg of urea were dissolved in 10 mL of water, which were transferred into a conical bottle heated in a domestic microwave oven for 5 min.…”

Zinc pyrovanadate nanorods with excellent peroxidase-like activity at physiological pH for the colorimetric assay of H2O2 and epinephrine

“…Nanozymes, as potential alternatives to natural enzymes, have aroused considerable interest owing to their highly catalytic properties and costeffectiveness, 17 when compared with natural enzymes. Currently, various nanomaterials including metal oxides, [18][19][20] metal sulfides, [21][22][23] noble metals, [24][25][26] metal-organic frameworks [27][28][29] and carbon nanomaterials [30][31][32] have been developed. Nevertheless, most of the reported nanozymes usually exhibit a higher activity only under acidic conditions ( pH < 5).…”
