“…These NPs offer specific advantages depending on the target analyte and the desired sensing mechanism. The fabrication of NPs-based Schiff base chemosensors involves synthesizing or functionalizing NPs with Schiff base ligands [124]. The choice of ligands depends on the target analyte and the desired binding properties.…”

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.

Honey bee venom from Apis species has garnered considerable attention in medicine due to its bioactive, which have antimicrobial activity. This research aims to isolate bioactive melittin and phospholipase A2 (PLA2) of honey bee venom from Indonesian Apis cerana and examine the antibacterial activity of these bioactive. Honey bee venoms were isolated from four locations using an electric shock method and purified using Fast Protein Liquid Chromatography. Purified protein was analyzed by SDS PAGE and measured by the Lowry method. Further, the antibacterial activity of melittin and PLA2 against Gram-positive (Staphylococcus aureus and Salmonella typhi) and Gramnegative (Escherichia coli) bacteria was defined by inhibition zone. Our results show that the average of all bee venoms obtained from four locations with eight sampling times was 17.1 mg proteins. Melittin was purified using gradient steps with 55%, 90%, and 100% elution buffer, while PLA2 was purified using 55% elution buffer. Melittin and PLA2 showed molecular weights of less than 7.5 kDa and 19 kDa, respectively. Protein concentrations in melittin and PLA2 were 95 µg/mL and 142 µg/mL, respectively. Among the two bioactive, only PLA2 showed antibacterial activity. The diameter of the inhibition zone was 7.76 mm when the concentration of PLA2 was 45 µg/mL against E.coli. This result showed that PLA2 from Indonesian Apis cerana has antibacterial activity and may be a promising candidate for the antibacterial agent on Gram-negative bacteria. These findings may contribute to developing new antibacterial substances derived from Indonesian Apis cerana.

“…Processes using green synthesis do not pose high energy requirements or the usage of specialized equipment (Sankar et al, 2014;Rajesh et al, 2018), leading to a significant reduction in cost. They are also efficient and have less reaction time (Omar et al, 2020). Work on such processes using plant extracts needs to be intensified to scale it up for industrial production.…”

This paper reports the green synthesis of Copper Oxide nanoparticles (CuO NPs) using Aquilaria malaccensis (agarwood) leaf extract. The main objective of this study was to evaluate the potential of using A. malaccensis leaf extract as a biogenic medium to generate CuO NPs with antimicrobial potential. The procedure employed was to add 5 mM copper sulfate (CuSO4.5H2O) as the precursor to A. malaccensis leaf extract to study the generation of CuO NPs under different incubation conditions such as methods of crude extract preparation, precursor concentration and incubation temperature. The results demonstrated that the boiled leaf extract reacted with 5 mM CuSO4.5H2O at pH 6 and incubated under non-shaking conditions at 70 °C, resulting in a high rate of CuO NPs formation and depicting a UV absorbance peak of 430 nm. Green synthesized CuO NPs were characterized using field emission scanning electron microscopy (FESEM) and energydispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and transmission electron microscopy (TEM). FESEM and TEM revealed that the nanoparticles are mainly spherical, ranging from 6 to 32 nm. Antimicrobial studies showed that 20 µL and 40 µL of 70 µg/µL CuO NPs displayed potent inhibition towards Gram-positive bacteria Bacillus subtilis, with the average zone of inhibition measuring 24.43 ± 0.10 mm and 27.31 ± 0.13 mm, respectively.
