• nanosheets [92]. The photothermal properties of two-dimensional black phosphorous nanosheets was first utilized by Ren et al. in LFAs for the sensitive detection of norfloxacin in tap water. The nanoscale complex of magnetic upconversion particles and black phosphorus has a characteristic brown colour that

• analytes within 20 min [91]. The utilization of black phosphorous nanosheets in LFA showcases its potential for sensitive and visual detection of norfloxacin in tap water. Although the LOD is higher than that of the GNP-based assay, the development of an integrated system of mobile phone camera and laser

• thought to be the cause of this. A higher degradation efficiency was noted at basic pH using Bi2WO6 to degrade norfloxacin under simulated sunlight [188]. The higher removal was attributed to a potential reaction between the photogenerated holes and hydroxyl ions at basic pH, which may have produced more

• with stabilizing agents. We hypothesize that, zwitterionic drugs like norfloxacin (NOR, a fluoroquinolone) can manifest dual functionality – nanoparticle stabilization and antibiotic activity, eliminating the need of a separate stabilizing agent. Since these drugs have different charges, depending on

• , IONPs, through their surface Fe2+/3+ moieties, could exhibit significant drug loading and therefore, have potential as fluoroquinolone delivery agents. Norfloxacin (NOR), the most basic fluoroquinolone [23] also exhibits anti-mycobacterial activity [24]. It chemically consists of a quinolone carboxylic
