Manufacture of Nanoparticles from the Belangkas Shell (Tachypleus Gigas) with Tripolifosphate Charged with Metal Ion Zn2+ for the Bacterial Activity Test
Introduction
The increasing demand for natural-based antibacterial materials has led to the exploration of various sources for the production of chitosan nanoparticles. Recent research has shown that the Belangkas shell (Tachypleus gigas) can be a potential source of raw material for making chitosan nanoparticles. This study aims to investigate the antibacterial activity of chitosan nanoparticles modified with tripolifosphate charged with metal ion Zn2+ against Escherichia coli and Stapylococcus aureus.
Background
Chitosan is a biodegradable and non-toxic polymer derived from the deacetylation of chitin, a polysaccharide found in the exoskeletons of crustaceans, including the Belangkas shell. Chitosan nanoparticles have been widely studied for their potential applications in various fields, including medicine, food, and pharmaceuticals. The addition of tripolifosphate and metal ions to chitosan nanoparticles can enhance their antibacterial activity.
Materials and Methods
The Belangkas shell was collected and processed to obtain chitosan. The chitosan was then dissolved in acetic acid and mixed with tripolifosphate to form nanoparticles. The nanoparticles were then charged with metal ion Zn2+ using a ion exchange method. The antibacterial activity of the nanoparticles was tested using a disc-diffusion method against Escherichia coli and Stapylococcus aureus.
Results
The results showed that chitosan nanoparticles and nanoparticles published with Zn2+ metal ions have antibacterial activity against both types of bacteria. However, Escherichia coli was more sensitive to this treatment compared to Stapylococcus aureus. The diameter of the clear zone (zone of bacterial growth resistance) in Escherichia coli was 14.3 mm, while in Stapylococcus aureus it was 11.4 mm. The antimicrobial index in Escherichia coli was 1.38, while in Stapylococcus aureus it was 0.90.
Discussion
The increased antibacterial activity of the nanoparticles published with Zn2+ metal ions is thought to occur due to the strong antibacterial properties of Zn2+. Zn2+ can increase the ability of chitosan to bind and penetrate bacterial cell walls, interfere with bacterial metabolic processes, cause damage to cell membranes, and ultimately inhibit bacterial growth.
Conclusion
This research opens new opportunities in the development of natural-based antibacterial materials. Chitosan nanoparticles modified with Zn2+ metal ions have great potential to be applied as antibacterial materials in various fields, such as the food, pharmaceutical, and health industry. Further research is needed to optimize the synthesis and characterization methods of this material, as well as to test their safety and effectiveness in various applications.
Future Directions
Future research should focus on optimizing the synthesis and characterization methods of chitosan nanoparticles modified with Zn2+ metal ions. This includes studying the effects of different concentrations of Zn2+ on the antibacterial activity of the nanoparticles, as well as testing their safety and effectiveness in various applications. Additionally, the potential applications of these nanoparticles in various fields should be explored, including their use as antibacterial coatings, packaging materials, and medical devices.
