PEI-stabilized gold nanoclusters provide optimized fluorescence properties, superior biocompatibility, and enhanced colloidal stability. Designed for advanced applications, they ensure efficient dispersion, extended durability, and high-performance adaptability.
Product Overview
PEI-stabilized gold nanoclusters (PEI-Au NCs) are nanomaterials composed of gold atoms, where the core of the nanocluster consists of several to dozens of gold atoms, and the surface is capped with polyethyleneimine (PEI). As a positively charged hyperbranched polyamine, PEI not only enhances the stability of the gold nanoclusters but also provides them with strong fluorescence properties across a wide pH range, making them suitable for various biomedical applications.
Features
- Optical Properties: PEI-Au NCs exhibit fluorescence properties that depend on their size, giving them significant potential for applications in bioimaging and fluorescence probing.
- Stability: The encapsulation by PEI gives the gold nanoclusters high stability in physiological environments, reducing aggregation or degradation.
- Positive Charge: The positive charge of PEI enables the gold nanoclusters to easily bind with negatively charged materials, increasing their potential for biological applications.
Applications
- Bioimaging: As fluorescent nanomaterials, PEI-Au NCs can be used for cell imaging, tissue imaging, and tumor imaging in biomedical research.
- Drug Delivery: PEI-Au NCs can serve as a drug delivery system. Their surface is easy to modify, allowing effective drug loading and targeted delivery.
- Chemical Detection: PEI-Au NCs are sensitive to specific chemicals and are widely used in environmental monitoring, food safety, and biomarker detection.
