Nanomaterial Surface Chemistries
Surface chemistry plays a critical role in determining dispersion stability, optical peak position, and compatibility with optical system environments. nanoComposix experts work with you to select surface options to preserve critical optical properties and support downstream integration.
| Surface Chemistry | Description |
|---|---|
 |
Citrate provides stabilization in aqueous systems while allowing strong coupling of nanoparticles with their surroundings. A highly modular surface chemistry to allow downstream modification for use in optical characterization, spectroscopy, and early-stage prototyping. |
 |
Silica coatings improve chemical, thermal, and mechanical robustness while maintaining the optical response of the core nanoparticle. Suitable for integration into coatings, composites, and optical materials. Silane modification of particles or silica coatings adds additional chemical flexibility for modification, assembly, and spacing. |
 |
Polymers such as poly(ethylene glycol) (PEG) reduce non-specific interactions and aggregation in biological systems, supporting long-term colloidal stability in optically sensitive systems. Others, such as Polyvinylpyrrolidone (PVP) provide good stability in more volatile solvents for spin coating. |
 |
Carboxyl groups enable robust covalent bioconjugation via established coupling chemistries (e.g., EDC/NHS), allowing attachment of antibodies, enzymes, peptides, and nucleic acids. This supports controlled biofunctionalization for targeted recognition and signal transduction in optical and electrochemical biosensing platforms. |
 |
The surface functionality of materials can be further customized to provide compatibility in specific solvent systems or to introduce reactive functional groups for conjugation or composite formation. |

FAQ: Optical Nanomaterials
Can nanoComposix help me select the right nanoparticle for my application?
Yes. nanoComposix provides technical guidance for many nanoparticle-enabled applications and routinely help customers map performance requirements to particle composition, size, and shape. Connect with our team to discuss your application.
How do you ensure batch-to-batch reproducibility?
We rigorously control the synthesis of each batch and provide extensive characterization to support consistent performance in your application. Characterization methods are particle-specific, but we provide batch-specific Certificates of Analysis including:
- Size and stability – TEM, DLS
- Surface charge – Zeta potential
- Concentration – ICP-MS, mass balance
- Optical properties – UV-Vis
What resources do you have to support application integration?
Our optoelectronic nanomaterial experts guide selection of nanomaterial platform, size, morphology, and surface chemistry – connect with our team to start the conversation. Our Knowledge Base also contains support such as spin coating protocols for select materials.
What customization options do you offer?
We frequently collaborate with customers on application-focused challenges – our extensive catalog can be modified to fine tune optical properties, surface chemistry, concentration, and solvent, along with developing fully custom solutions outside our catalog. Our experience allows us to act as your technical partner, not just a materials supplier. Connect with our team to discuss your particle requirements.
Do you offer refractive index tuning for optical applications?
Yes. We support refractive index tuning by tailoring material, size, and surface chemistry to achieve targeted optical performance. Whether you need to increase scattering, improve light transmission, or fine-tune optical performance within a multilayer stack, we work with you to optimize materials for your design and process. Connect with our team to discuss your application.
Can nanomaterials be uniformly integrated into thin films or multilayer optical stacks?
Yes. Our nanomaterials are produced as high-purity colloidal dispersions that integrate smoothly into thin films and multilayer optical stacks using standard coating processes. Their stable, monodisperse nature prevents aggregation, ensuring uniform layers with predictable optical performance.
