Histamine is a well-known biogenic amine (BA) that often associated with allergic reactions and significant cause of foodborne illnesses resulting from the consumption spoiled food. Detecting histamine essential for maintaining food safety standards preserving quality. In this work, we developed simple, low-cost, rapid colorimetric method detecting histamine. Gold nanoparticles (AuNPs) different sizes (16, 25, 40 nm) were synthesized by using citrate reduction method. The particle size was...
Histamine is among the biogenic amines that are formed during microbial decarboxylation of amino acids in various food products, posing a significant threat to both safety and human health. Herein, we present one-step synthesis PEGylated gold nanoparticles (PEG-AuNPs) for rapid, simple, cost-effective colorimetric histamine detection. PEG-AuNPs' surface plasmon resonance (SPR) range at 520-530 nm with hydrodynamic size distribution 20-40 nm. Fourier transform infrared (FT-IR) spectra...
Histamine, a primary biogenic amine (BA) generated through the decarboxylation of amino acids, concentration increases in protein-rich foods during deterioration. Thus, its detection plays crucial role ensuring food safety and quality. This study introduces an innovative approach involving direct integration dopamine onto gold nanoparticles (DCt-AuNP), aiming at rapid histamine colorimetric detection. Transmission electron microscopy revealed aggregation uniformly distributed spherical...
We report on antibacterial activities of Zinc oxide (ZnO) with different structures. Fast furrier transform infrared spectroscopy ZnO nanostructures showed peaks in the range between 450–600 cm-1 indicating successful growth through presence Zn-O stretching. On other hand, impurities such as zinc complexes might be present due to appearance at 1110 cm-1, 1390 and 1506 cm-1. Furthermore, SEM images revealed that nanorods sea-urchin like are produced nanostructures. Nanorods exhibit a better...
