Ramanprobes™ Extrinsic SERS Labels

What are Ramanprobes™?

Ramanprobes™ are a novel product family that combines both gold nanoparticles and fluorophores into one construct. The construct exhibits extremely high sensitivites - down to 10 Femtomolar with a simple 10mW laser based Raman spectrometer. Nanopartz™ has developed chemistries that make this constuct exhibit the following benefits:

  • Very little background fluorescence.
  • Extremely high sensitivity with no photobleaching.
  • Enables the potential for both absorption, scattering, and SERS detection.
  • No gold surface required in sandwich assay format.
  • Homogeneous assay ability.
  • All the functionalizations for in vitro, in vivo, and organic applications.

Nanopartz™ Ramanprobes™ are available from 532nm to 850nm

Functionalized Ramanprobes™

Highly protected covalent polymer layer for a wide variety of pH and salt environments. Popular functionalizations include amine, biotin, carboxyl, methyl, neutravidin, streptavidin, nhs, maleimide, antibodies, secondary antibody conjugates, and oligos.

Ramanprobes™ for in vivo

Dual use particles for both SERS imaging and photothermal therapy.

Ramanprobes™ in Organic Solvents

Particles for use in organic solvents.

One-Step Kits: Ramanprobes™ for Antibody Conjugations

One step conjugations to any antibody, peptide, oligo, or other amine containing target.
