Hemocompatibility of Carbon-Dots from Lignin Oil Palm Empty Bunches: Evaluation of In-Vitro with the Hemolysis Method

Introduction

Lignin, a Valuable Resource for Carbon-Dots Synthesis

Lignin, the primary component of lignocellulosa biomass found in Oil Palm Empty Bunches (TKS), has immense potential that remains largely untapped. Rich in carbon, lignin can be utilized as a precursor in the synthesis of carbon-dots (C-Dots) nanoparticles. C-Dots possess several advantages over other fluorescent nanoparticles, including high biocompatibility and excellent solubility in water. These characteristics make C-Dots an attractive option for various biomedical applications.

The Importance of Hemocompatibility in Biomedical Applications

For C-Dots to be used in biomedical applications, they must meet the stringent requirement of hemocompatibility. Hemocompatibility is a critical factor in ensuring the safety and efficacy of nanoparticles in biological systems. In-vitro hemolysis studies have been proven to be highly predictive of in-vivo studies, providing valuable insights into the potential for hemolysis and pro-inflammatory responses associated with nanoparticles.

Objectives and Methodology

Evaluating the Hemocompatibility of C-Dots Synthesized from Lignin TKS

This study aims to evaluate the hemocompatibility of C-Dots synthesized from lignin TKS using the in-vitro hemolysis method. Additionally, this study investigates the effect of increasing C-Dots concentration on the percentage of hemolysis.

In-Vitro Hemolysis Method

The in-vitro hemolysis method employed in this study involves incubating human blood with C-Dots of varying concentrations (10 mg/ml, 1 mg/ml, 0.2 mg/ml, and 0.04 mg/ml) for approximately 3 hours. The hemocompatibility of C-Dots is assessed using spectrophotometry with a microplate reader at a wavelength of 540 nm. The observed percentage of hemolysis is calculated as a percentage of hemolysis.

Results and Discussion

Hemocompatibility of C-Dots Synthesized from Lignin TKS

The results of this study demonstrate that C-Dots synthesized from lignin TKS exhibit excellent hemocompatibility. The highest percentage of hemolysis observed was 1.65%, while the lowest was 0%. These findings meet the international standard requirements of ASTM E2524-08. Although C-Dots do not cause significant hemolysis, an increase in concentration correlates with an increase in the percentage of hemolysis.

Implications and Future Directions

The hemocompatibility of C-Dots synthesized from lignin TKS opens up opportunities for their use as safe biomedical materials. These nanoparticles have the potential to be applied in various fields, including cell imaging, drug delivery, and photodynamic therapy. However, further research is necessary to comprehensively evaluate the safety and effectiveness of C-Dots from lignin TKS, including in-vivo studies and pro-inflammatory potential analysis.

Conclusion

Nanoparticles C-Dots from Lignin TKS: A Promising Biomedical Material

In conclusion, nanoparticles C-Dots from lignin TKS exhibit excellent hemocompatibility and do not cause hemolysis of red blood cells through the study of in-vitro hemolysis methods. These findings provide a solid foundation for the development of C-Dots as a safe and effective biomedical material.

Future Research Directions

Comprehensive Evaluation of C-Dots from Lignin TKS

Further research is needed to evaluate the safety and effectiveness of C-Dots from lignin TKS more comprehensively. This includes in-vivo studies to assess the biocompatibility and toxicity of C-Dots in living organisms. Additionally, pro-inflammatory potential analysis is necessary to ensure that C-Dots do not induce adverse immune responses.
