The Power of Gold Nanomaterials
Gold nanomaterials have become a multifunctional and powerful tool in modern science and technology due to their unique physical and chemical properties. For example, the localized surface plasmon resonance (LSPR) of gold nanoparticles makes them an ideal choice for biosensing and medical imaging applications. Their excellent biocompatibility and low toxicity are highly suitable for drug delivery and therapeutic applications. In addition, the catalytic activity and high surface area to volume ratio of gold nanoparticles make them excellent catalysts for various chemical reactions.
At CD Bioparticles, we utilize these characteristics by carefully controlling key parameters:
- Size: The size of gold nanoparticles directly affects their optical, electronic, and catalytic properties. We can precisely control the particle size from a few nanometers to several hundred nanometers, allowing you to fine tune the properties of materials for specific applications.
- Shape: In addition to simple spheres, we can also manufacture various gold nanostructures, including nanorods, nanostars, nanocages, nanoshells, and nanoplates. Each shape has unique LSPR characteristics and surface area, providing unique advantages for different applications.
- Surface chemistry: The surface height of gold nanoparticles can be customized. We provide various surface modification services, including coupling with biomolecules (antibodies, proteins, DNA), PEGylation to improve stability and biocompatibility, and coating with different polymers or small molecules.

We understand that every project is unique. Our service is highly flexible and offers a wide range of customization options to perfectly match your needs.
Customized Shape of Gold Nanoparticles
- Gold nanospheres: The most common form, with sizes ranging from 5 nm to 200 nm, allowing for precise control of monodispersity.
- Gold nanorods: adjustable aspect ratio, allowing for precise control of their LSPR peak, making them an ideal choice for photothermal therapy and SERS.
- Gold nanostars: with multiple sharp tips, they are highly suitable for enhancing local electric fields, which are crucial for SERS and catalysis.
- Gold nanocages/nanoshells: Hollow or core-shell structures with tunable plasmon resonance in the near-infrared (NIR) region, highly suitable for biomedical imaging and photothermal applications.
- Gold nanosheets: anisotropic two-dimensional structures with unique optical properties and large surface area.
Advanced Surface Functionalization
The surface of gold nanomaterials can be customized to give specific functions. We provide various surface modification services to improve stability, target specific cells, or attach functional molecules.
- Bioconjugation: Direct covalent linkage of antibodies, proteins, peptides, nucleic acids, and other biomolecules for targeted drug delivery, diagnosis, and biosensing.
- PEGylation: Polyethylene glycol (PEG) chains covalently attach to the surface of nanoparticles to enhance stability in biological media, reduce non-specific binding, and prolong in vivo circulation time.
- Polymer coating: Encapsulated with various polymers to enhance stability, provide specific functionality, or manufacture multifunctional composite materials.
- Small molecule functionalization: Small molecules are covalently linked for specific purposes, such as targeting ligands, fluorescent groups, or catalytic sites.
