Frequently Asked Questions

Your questions answered

How are Sona’s CTAB-free gold nanorods different from other CTAB-free gold nanorods?

Sona does not use CTAB or any of its homologs to produce its gold nanorods (GNRs). This means that no traces of CTAB or CTAare present in the GNRs after production. Other suppliers make GNRs in CTAB or is its analogs and then attempt to remove excess CTAB, or wrap their GNRs in polymers with CTAB still remaining on them.

What kind of characterization information does Sona provide?

Sona provides characterization information with every lot including size, optical properties (UV-Vis to near IR spectroscopy), zeta potential (Dynamic Light Scattering). Representative TEM images and batch-specific spectra are also included on every product sheet.

What is the shelf life of Sona’s gold nanorods?

Sona’s gold nano rods (GNRs) remain stable for at least a year. Please see our technical specification sheets for information on best practices for storage and handling.

Does Sona collaborate with other organizations/universities?

Sona is actively seeking collaborations with lateral flow test developers or developers of any medical applications using GNRs or where GNRs may prove to be the appropriate particle. Sona is always willing to discuss collaborations. To begin the process of collaborating, please contact us.

What applications can Sona’s gold nanorods be used for?

SONA’s gold nanorods are designed with life science applications in mind, such as:

  • Photothermal / hyperthermal therapy
  • Bio-imaging (3D)
  • Diagnostic test kits
  • Pain management
  • Liposuction

SONA’s gold nanorods are also suitable for research in:

  • Data storage
  • Solar cell technology

Please contact us for further information regarding the use of our particles for your desired application.

What benefits do Sona’s gold nanorods offer?

Sona has a patent-pending manufacturing process that produces stable, monodispersed gold nanorods. Our customers can achieve better results due to the uniformity in rod shape, and the reproducibility that our method provides.

Sona’s CTAB-free gold nanorods versus conventional gold nanorods

Sona’s CTAB-free gold nanorods (GNRs) are safe for in-vivo uses. Thus, if the aim of specific research is to be approved for human trial, Sona’s nano rods offer the best chance. Further, Sona’s GNRs have superior uniformity. The surface molecules of the GNRs exchange more easily with other molecules to make surface enhancement and functionalization easier.
