“…The scavengers were applied to determine the role of active oxygen species in the photocatalytic degradation of RB5 dye under a 365 nm UV beam for 120 min, which can properly propose its possible degradation pathway. 38,39,74 All scavengers were tested at the same concentration (1.0 mM), with 1.0 g L −1 of ZIF-8-F3 catalyst and 20 mg L −1 of aqueous RB5 solution at pH = 7.0. In typical, isopropyl alcohol (IPA), ethylenediaminetetraacetic acid (EDTA), potassium persulfate (K 2 S 2 O 8 ), and 1,4-benzoquinone (BQ) were used for trapping ˙OH radicals, holes (h + ), electrons (e − ), and superoxide radical anions (˙O 2 − ), respectively.…”

“…In addition, the increased intensity in the UV region may be due to the charge transfer from the valence band (VB) to the conduction band (CB). 25,38 The band gap energy plays a crucial role in determining the optical properties of materials. The mathematical equation of this energy can be expressed according to the Kubelka-Munk formula as: ahn = A(hn − E g ) 2 , 63 where a is the absorbance, h is the Planck constant, n is the frequency of light, A is the proportionality constant, and E g is the bandgap energy.…”

“…Although in previous studies ZIF was capable of disturbing S. aureus and E. coli biofilms, in this study, the increasing concentrations of ZIF/LDH were associated with reduced biofilm formation. It has been shown that imidazolate rings in ZIF are capable of absorbing crystal violet, which suggests ZIF for removing crystal violet impurities from water samples [34, 35]. Therefore, it is hypothesized that increased OD values in ZIF/LDH‐treated wells are related to crystal violet absorption which can be considered a factor of interference in in‐vitro studies [36].…”

Biofilms represent longstanding challenges to oral health care. Candida albicans and Streptococcus mutans are the common pathogens forming biofilms. The growing resistance to and the adverse effects of antibiotics limit their usage and raise the need for novel approaches. Herbal extracts have emerged as efficient choices with lower costs and fewer adverse effects. Metal frameworks have captivated interest due to their high surface area, special biocompatibility, and non‐toxicity. The effects of zeolitic imidazolate frameworks/layered double hydroxide (ZIF/LDH) on fungal infections and the potential effects of Eremostachys binalodensis on bacteria encouraged the researchers to evaluate the effect of ZIF/LDH, E. binalodensis, and their combination on C. albicans and S. mutans biofilms. ZIF/LDH nanocomposite was synthesized and characterized using scanning electron microscopy, Fourier transform infrared spectra, and X‐ray diffraction to assess morphology and chemical structure. Methanol extracts of the areal parts of E. binalodensis were obtained by Soxhlet extraction. The microdilution tests and biofilm crystal violet staining were applied. Concentrations of 2.048 and 4.096 mg/ml E. binalodensis prevented C. albicans and S. mutans biofilm formation. The combination of ZIF/LDH + E. binalodensis prevented C. albicans and S. mutans biofilm formation. This research suggests the use of E. binalodensis‐loaded ZIF/LDH nanocomposites for removing biofilms.

Crystal violet (CV), a cationic dye, has been demonstrated to be a powerful carcinogen, a mitotic toxin and poisonous to mammalian cells such that the predominant presence of the dye invariably causes several effects of destruction to mankind and it necessitates a clarion call to do away with this nuisance before it can produce a snowball effect. The recent widespread reporting of the photocatalysis‐mediated degradation of CV as an emerging technique for removing this dangerous dye from aqueous mediums highlights its effectiveness. Numerous researchers have contributed substantially to describing how photocatalysis‐based nanomaterials could be used to degrade CV. The fundamentals and the factors that predominantly influence CV degradation are highlighted in this work. These factors include the nature of nanomaterials, catalyst concentration, dye dosage, pH of the solution in use, temperature and light intensity. Additionally, thorough kinetics and mechanistic descriptions are also included to give crucial insights into the light‐mediated reaction of CV. The present study's findings have the potential to alleviate practitioners and researchers of the burden of having to navigate through numerous studies under each category of parameters to get an exhaustive overview of all of the different variables that may affect the photocatalytic degradation of CV dye. In order to further enhance the photocatalytic degradation efficiency of CV, researchers can expand on this study by investigating novel strategies to lessen the impact of certain elements that adversely affect the photocatalytic reaction process. The potential prospects for extending the advancement of scientific study in this area are also explored. © 2024 Society of Chemical Industry (SCI).
