Key Advantages
High Surface Area
The 30 nm particle size provides a large available surface area for biomolecule adsorption, surface functionalization and assay development.
Easy Surface Modification
Surface silanol groups can be used for silanization and further chemical modification, supporting the development of amino, carboxyl and other functional surfaces.
Good Chemical Stability
The silica matrix offers good resistance to common assay buffers and supports stable use in a wide range of research conditions.
Nanoscale Dispersibility
Controlled production helps provide a consistent nanoscale dispersion for repeatable formulation and assay evaluation.
Batch Production Support
SHBC supports research samples, pilot testing and larger-volume supply for diagnostic reagent manufacturers and research institutions.
Immunoassay Applications
Si30NM-10 Silica Microspheres can be evaluated for:
Antigen and antibody adsorption studies
Immunoassay carrier development
Biomolecule immobilization
Biosensor and diagnostic reagent research
Surface functionalization studies
Signal amplification system development
Protein and peptide adsorption
Nucleic acid and biomolecule detection research
Nanoparticle labeling and conjugation studies
In vitro diagnostic raw material development
Actual performance should be optimized according to the biomolecule, buffer, pH, ionic strength and coupling method.
Why Use 30nm Silica Microspheres?
Compared with larger silica particles, 30 nm silica microspheres provide a higher surface area per unit mass. This can be useful when developing assays that require increased surface interaction or nanoscale carrier materials.
Their small size also makes them suitable for:
High-surface-area adsorption studies
Compact biomolecule carrier systems
Nanoscale biosensor development
Surface chemistry screening
Diagnostic nanoparticle formulation
Suitable for Physical Adsorption and Surface Functionalization
The silica surface contains silanol groups that can interact with proteins and other biomolecules. Si30NM-10 can be used for preliminary physical adsorption studies or as a base material for further surface modification.
For improved binding stability, researchers may evaluate silane modification or covalent coupling methods according to the target biomolecule.

Frequently Asked Questions
What are 30nm silica microspheres used for?
They are commonly evaluated as nanoscale carriers for immunoassay research, biomolecule adsorption, surface modification, biosensors and diagnostic reagent development.
Can antibodies be adsorbed onto the silica surface?
Physical adsorption can be evaluated, but the result depends on antibody properties, buffer composition, pH and ionic strength. Surface modification or covalent coupling may provide better binding stability.
Can the surface be functionalized?
Yes. Surface silanol groups provide a foundation for silanization and further introduction of amino, carboxyl or other functional groups.
Why choose 30 nm instead of larger silica microspheres?
The smaller particle size provides a higher surface-to-volume ratio, which can be useful for surface interaction, biomolecule loading and nanoscale assay development.
Is Si30NM-10 suitable for commercial reagent production?
The product is intended for research use. SHBC can support pilot testing and bulk production for customers developing commercial reagents. Customers should complete application-specific validation and regulatory evaluation.
Can SHBC provide custom concentrations?
Custom solid contents and packaging formats can be discussed according to project volume and technical requirements.
Are bulk quantities available?
Yes. Shanghai SanYu Biotechnology Co., Ltd. supports sample evaluation, pilot-scale orders and batch manufacturing.
