In this work, we used chitosan as a raw material to synthesize carbon dots using fast microwave carbonization. We studied the influence of the synthesis time, doping agent, and the molar ratio between the reactants on the quantum yield of carbon dots. Chitosan-based carbon dots displayed stable blue fluorescence emission with excitation-dependent behavior and quantum yield values ranging from 1.

- Cardanol, a key component of cashew nut shell liquid, has antioxidant and antibacterial properties that can be enhanced through encapsulation.
- The study involves isolating cardanol and creating nanoparticles using biocompatible and biodegradable materials like chitosan and sodium alginate.
- Characterization reveals the nanoparticles have a spherical shape, are mostly between 34 to 300 nm in size, and demonstrate improved antioxidant potential compared to pure cardanol, suggesting they could effectively target and deliver its active properties in various applications.
