Excellent gold nanoparticle quality! They exhibit a high degree of stability and consistency, which are critical factors for our research. The nanoparticles meet our quality control standards, ensuring reproducibility of our experiments. The Nano Flow’s gold particles enabled us to explore and develop new methodologies and applications in the field of colorimetric detection, advancing our research capabilities. The high-quality nanoparticles have led to more sensitive detection of various small molecules, reducing variability and enhancing the reliability of our data.

NanoFlow custom conjugation process has been working smoothly and the customer service has been excellent. The custom conjugates have been working as expected and the stability is fine.

The stability of the Nano Flow gold colloids over time is better when compared with different suppliers. The package shipment is always proceeded in proper conditions and the product finds our internal quality check well. It is not so obvious with other products and suppliers.

Contact with NanoFlow is adequate, team members were always helpful and dedicated to find a solution to any problem that we had. Therefore, we can rate the overall quality very high.

We used 40nm gold particles to passively conjugate a protein that did not absorb to other commonly used gold particles. The conjugate was stable, specific, and sensitive. The protocol is long, especially when it comes to pH adjustment, but worth the effort.

we tried the Nano Flow gold nanoparticles not exactly with the same protocol they provided but with a similar one, and we compared these nanoparticles to those from two different suppliers. They perform better than the others, showing less cross-reactivity and greater stability.

Very high quality and stability of gold nanoparticles. Comprehensive certificate of analysis. Competitive pricing. Fast delivery and a European company, which is an advantage compared to US-based suppliers with typically longer lead times.

We found the gold particles of high quality with all the information needed for a research study. Certificate of analysis, exact size and count of gold particles per mL and higher OD with long shelf life was important for our study. Nanoflow provided us with everything in addition to good customer support.

Very stable gold particles. We have not yet encountered any aggregation problems with them and also observed that there is no lot-based quality difference. Their nanoparticles can be easily adapted to other protocols and can be easily used in alternative conjugation methods.

We chose the Nano Flow gold nanoparticles because of their remarkable stability. Even after a long period, their performance remains consistently reliable. Since switching to these nanoparticles, our signals have become much clearer, with bright and distinct colors. We have also noticed that our conjugates are significantly more stable compared to when we used other nanoparticles.
