Collection: Gold Nanoparticles - Spherical, Citrate Surface

Citrate Gold Nanoparticles for Biotech Research

NanoBrand citrate gold nanoparticles are highly monodisperse spherical colloidal gold materials designed for demanding biotechnology applications, including biomedical diagnostics, biosensing, imaging, drug delivery systems, and cancer therapy studies. They provide a stable, well‑characterized starting point for nanoparticle‑based assays, and their citrate‑stabilized surface offers long‑term dispersion stability and a versatile platform for bioconjugation, making these citrate gold nanoparticles a reliable choice for reproducible, high‑quality experiments.

Multi‑Size Citrate Gold Nanoparticles for Flexible Assay Design

Our citrate gold nanoparticles are available in multiple core sizes, allowing researchers to select the optimal particle diameter for their specific assay format, detection method, or biological model. The citrate surface offers long‑term dispersion stability and a versatile platform for further functionalization, as it can be readily displaced or modified to attach antibodies, peptides, nucleic acids, polymers, or other ligands.

Monodispersity, Reproducibility, and Quality Control

The narrow size distribution of these citrate‑stabilized gold nanoparticles ensures consistent optical properties, predictable behavior in biological systems, and more reproducible data across experiments. Scalable synthesis procedures and rigorous quality control testing provide lot‑to‑lot consistency, making NanoBrand citrate gold nanoparticles a dependable choice for scientists who require reliable, high‑quality colloidal gold for biosensing, imaging, and therapeutic research.
