Amine Gold Nanoparticles are high-quality gold nanoparticles that have been precisely functionalized with amine-terminated polyethylene glycol (PEG). This specific functionalization makes them ideal for various advanced research and diagnostic applications.

Key Features and Properties:

• Bioconjugation Ready: The amine surface allows for convenient and robust covalent conjugation to carboxyl-terminated molecules. This enables researchers to attach a wide range of biomolecules such as antibodies, proteins, or DNA.
• Size Range: Available with a versatile core diameter ranging from 4 nm to 200 nm, providing flexibility for different experimental needs.
• Optical Properties: Exhibit a characteristic absorbance peak between 520 – 850 nm, confirming their gold nanoparticle nature and allowing for spectrophotometric detection.
• Stability: Boast a shelf life of over 1 year when stored correctly at 4°C, ensuring long-term utility.
• Supplied Form: Provided as a stable liquid suspension in PBS (Phosphate-Buffered Saline) or in water containing 0.01% (w/v) Tween-20, ready for immediate use.

Applications of Amine-Functionalized Gold Nanoparticles: Due to their highly reactive amine surface, these gold nanoparticles are widely used in a variety of scientific fields, including:

1. Biosensing: For developing highly sensitive and specific biosensors through the immobilization of recognition molecules (e.g., antibodies, aptamers).
2. Diagnostic Assays: As labels in various diagnostic tests, such as lateral flow assays or immunoassays, due to their optical properties and ability to conjugate.
3. Targeted Drug Delivery: In experimental systems for attaching targeting ligands to direct drugs to specific cells or tissues.
