Gold Nanoparticle & Quantum Dot Bioconjugation
Connect nanoparticle design and bioconjugation to the signal, stability and workflow your assay needs.
Development scope
From the first question
to the next milestone.
02Surface chemistry
Evaluate surface functionalisation, coatings and colloidal behaviour in the intended assay environment.
03Bioconjugation
Develop coupling conditions for suitable recognition reagents and evaluate binding activity and non-specific interactions.
04Assay integration
Assess conjugate performance in the target workflow, including signal, background and compatibility with storage conditions.
Technical perspective
What matters in development
The particle surface and coupling method can influence binding activity, colloidal stability and non-specific signal. We develop nanoparticle labels in the context of the intended assay, including antibody conjugation and downstream readout.
Common project questions
Do you work with gold and fluorescent labels?
Yes. Projects may evaluate gold nanoparticles or fluorescent quantum dots according to the required readout and assay workflow.
Can you evaluate a conjugate in our assay?
Yes. Assay integration can include signal, background and compatibility checks under the conditions agreed for the project.
