Method & Evidence

AimTo investigate the potential of silver nanoparticles synthesized using pineapple peel extract for biomedical applications, including antioxidant, antibacterial, antidiabetic, and cytotoxic activities.

MethodExperimental synthesis and characterization of nanoparticles, followed by in vitro biological assays.

ProcedureSilver nanoparticles (AgNPs) were synthesized using an extract from the outer peel of Ananas comosus. The synthesized AgNPs were characterized using UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). The biological potential of these AgNPs was then evaluated through assays for antioxidant activity, antidiabetic activity, cytotoxicity against HepG2 cells, and antibacterial activity against four foodborne pathogens.

ContextBiomedical materials synthesis, waste valorization, green nanotechnology.

Variables

IVPineapple peel extract (as a reducing and stabilizing agent).

DVAntioxidant activity, antibacterial activity, antidiabetic activity, cytotoxicity of synthesized silver nanoparticles.

CVConcentration of silver ions, reaction time, temperature, pH (potentially).

Strengths & Limitations

Strengths

+Utilizes a waste material, promoting sustainability.
+Demonstrates multiple beneficial biological activities of the synthesized nanoparticles.
+Employs standard characterization techniques for nanoparticles.

Limitations

The study was conducted in a lab setting; real-world applications might face challenges in scaling up production or ensuring consistent quality.

Reliability & validity

The use of multiple characterization techniques (UV-Vis, XRD, FT-IR, SEM, EDX) enhances the validity of the nanoparticle synthesis claim. Biological assays were conducted, but details on replication and statistical analysis would be needed to fully assess reliability.

Think critically

How might the variability in pineapple peel composition affect the consistency and efficacy of the synthesized nanoparticles?
