Encapsulating PbS quantum dots with ligands like 1-2 EDT (ethylenediaminetetraacetic acid) can help improve their stability, prevent aggregation, and provide compatibility with various solvents or matrices. When it comes to choosing appropriate polymers for encapsulation, there are several options you can consider:

1. Poly(methyl methacrylate) (PMMA): PMMA is a widely used polymer for quantum dot encapsulation. It provides good stability, excellent film-forming properties, and can be easily processed using techniques such as spin-coating or solvent casting. Aayush Chadha I don,t know you have tried out this way or not?

2. Poly(ethylene glycol) (PEG): PEG is a biocompatible polymer that can be used for encapsulating quantum dots for biological applications. It can provide stability and facilitate water-soluble dispersion of the quantum dots.

3. Polyvinylpyrrolidone (PVP): PVP is another commonly used polymer for quantum dot encapsulation. It can provide good stability, prevent aggregation, and improve solubility in various solvents.

4. Poly(lactic-co-glycolic acid) (PLGA): PLGA is a biodegradable and biocompatible polymer that can be used for encapsulation of quantum dots. It is often used in controlled-release applications.

5. Polystyrene (PS): PS is a widely used polymer with good film-forming properties. It can be used for encapsulation of quantum dots and provides stability and compatibility with various solvents.

These are just a few examples of polymers that can be used for encapsulating PbS quantum dots with ligands like 1-2 EDT. It's important to note that the choice of polymer will depend on your specific application requirements, such as desired properties, solubility, compatibility, and processing techniques. Additionally, you may need to consider surface modification techniques to ensure proper interaction between the ligands on the quantum dots and the encapsulating polymer.

Dear Aayush,

Yes, there are a number of polymers that can be used to encapsulate PbS quantum dots with 1-2 EDT ligands. Some of the most commonly used polymers include:

• Polyethylene glycol (PEG)
• Polyacrylamide (PAM)
• Polymethacrylate (PMMA)

EDTA ligands provide you a negative zeta-potential and a stabilization in aqueous invironment. Insofar a positively charged polymer can be attached tro the surface by the Layer-by-Layer process. Such polycations could be polyallylamine or polyfdimethyldiallyleamine). Other possibilities would be none-charged polymers like Polyvinylalkohol or polyvinylpyrrolidone or as already mentioned PEG.

Hi all, thank you for your inputs. Ultimately, SU8-6002 seemed to have worked well!
