“…Several nanocojugates, i.e., Schiff base complexes with zinc conjugated to silver nanoparticles, showed excellent antimicrobial activity against S. aureus [86]. A recent work by Minhaz et al (2020) [87] compared the activity of an SB (53) and silver nanoparticles of this compound (53-AgNPs), studied as nanoprobes. The latter exhibited significant antibacterial and anticancer activities and was also used as sensitive protocol for the detection and quantification of heavy metal Hg(II) in tap water.…”

Schiff bases (SBs) have extensive applications in different fields such as analytical, inorganic and organic chemistry. They are used as dyes, catalysts, polymer stabilizers, luminescence chemosensors, catalyzers in the fixation of CO2 biolubricant additives and have been suggested for solar energy applications as well. Further, a wide range of pharmacological and biological applications, such as antimalarial, antiproliferative, analgesic, anti-inflammatory, antiviral, antipyretic, antibacterial and antifungal uses, emphasize the need for SB synthesis. Several SBs conjugated with chitosan have been studied in order to enhance the antibacterial activity of chitosan. Moreover, the use of the nanoparticles of SBs may improve their antimicrobial effects. Herein, we provide an analytical overview of the antibacterial and antifungal properties of SBs and chitosan-based SBs as well as SBs-functionalized nanoparticles. The most relevant and recent literature was reviewed for this purpose.

“…Whether the probe can retain its sensitivity over time and under various environmental conditions is crucial for its practical applications. Another example of how surface modification of nanoparticles improves performance is shown in Figure 16b, which illustrates probe-45 by Minhaz et al [114]. They stabilized the Schiff base ligand on silver nanoparticles for detecting Hg 2+ in the range of 0.01 µM to 50 µM.…”

“…Furthermore, integrating nanomaterials or auxiliary receptors has shown promise in amplifying the detection efficiency of Schiff base chemosensors. Nanomaterials, such as metal nanoparticles, carbon nanotubes, or quantum dots, provide unique optical and electronic properties that enhance chemosensors' sensitivity and signal amplification capabilities [114]. Researchers have improved selectivity, sensitivity, and stability by immobilizing the Schiff base chemosensors on the surface of these nanomaterials [115].…”

Toxic cations, including heavy metals, pose significant environmental and health risks, necessitating the development of reliable detection methods. This review investigates the techniques and approaches used to strengthen the sensitivity and selectivity of Schiff base fluorescent chemosensors designed specifically to detect toxic and heavy metal cations. The paper explores a range of strategies, including functional group variations, structural modifications, and the integration of nanomaterials or auxiliary receptors, to amplify the efficiency of these chemosensors. By improving selectivity towards targeted cations and achieving heightened sensitivity and detection limits, consequently, these strategies contribute to the advancement of accurate and efficient detection methods while increasing the range of end-use applications. The findings discussed in this review offer valuable insights into the potential of leveraging Schiff base fluorescent chemosensors for the accurate and reliable detection and monitoring of heavy metal cations in various fields, including environmental monitoring, biomedical research, and industrial safety.

“…Higher extinction coefficients, sharp extinction bands, a higher ratio of scattering to extinction, extremely high field enhancements, and instant responses give exceptional popularity to AgNPs. 30,31 The capacity of AgNPs to exhibit immediate color modification in response to different types of analytes, such as heavy metal ions, 32 pharmaceutical drugs, 33 and pesticides, 34 has sparked consequential interest in modifying the surface properties of AgNPs for sensing applications. The detection of neomycin using melamine modified gold nanoparticles was studied by Xiao et al by the observed color change from wine red to blue.…”
