We report a novel, simple, efficient, and green protocol for biogenic synthesis of silver nanoparticles (AgNPs) in aqueous solution using clove (Syzygium aromaticum) extract as a reducing and protecting agent. Ultraviolet-visible (UV-Vis) spectroscopy was employed to monitor the localized surface plasmon resonance (LSPR) band of clove extract-derived AgNPs prepared under various conditions. Fourier-transform infrared (FTIR) spectroscopy analysis provided information about the surface interaction of the clove extract with the AgNPs. Ultrahigh-resolution transmission electron microscopy (UHRTEM) results confirmed the formation of spherical, uniformly distributed clove extract-capped AgNPs with sizes in the range of 2–20 nm (average size: 14.4 ± 2 nm). Powder X-ray diffractometry analysis (PXRD) illustrated the formation of pure crystalline AgNPs. These AgNPs were tested as a colorimetric sensor to detect trace amounts of vinclozolin (VIN) by UV-Vis spectroscopy for the first time. The AgNP-based sensor demonstrated very sensitive and selective colorimetric detection of VIN, in the range of 2–16 µM (R2 = 0.997). The developed sensor was green, simple, sensitive, selective, economical, and novel, and could detect trace amounts of VIN with limit of detection (LOD) = 21 nM. Importantly, the sensor was successfully employed for the determination of VIN in real water samples collected from various areas in Turkey.

Cloves is one of the native Indonesian plants and is used in many aspects of life. Cloves are used in multiple industries and as detergents, soaps, perfumes, food seasonings, aromatherapy, etc. Cloves are mainly used for ingredients in kretek cigarettes in Indonesia. Various studies of cloves reported they have good pharmacological and therapeutic effects. The main compounds of clove extract are eugenol and β-caryophyllene, which are powerful antibacterial and antifungal agents. The clove ethanolic extract showed the activity to inhibit Gram positive and negative bacteria such as B. cereus, S. aureus, E. coli, P. aeruginosa, S. pneumoniae, S. aureus, S. epidermidis, A. hydrophila, K. pneumoniae, P. gingivalis, and P. mirabilis. Clove essential oil has shown the ability to inhibit the growth of V. inaequalis, C. albicans, C. glabrata, and C. tropicalis. Cloves extract can be used as an essential ingredient of various medicines. However, it requires further research and trials.
