No, we do not have pure gold substrates, only silver substrates covered with layer of gold nano-particles
Substrates with AgAu coverage provide more homogeneous results of SERS measurements (higher homogeneity)
Each of our products can be prepared according to your wishes with hydrophilic or hydrophobic properties
No, our substrates are ready to use
Yes, they are stored in argon conditions and additionally such eppendorf is stored in vacuum package
For reliable results we suggest to use substrates instantly after opening the package
UV-ozone or plasma cleaner should not influence surface of our substrates. But please remember not to use high temperatures because structure of silver will be destroyed, and our substrates are both silver based, therefore this rule is applied to both types of our substrates.
High temperatures will influence SERS properties negatively because the structure of silver will be destroyed, and our substrates are both silver-based, therefore this rule is applied to both types of our substrates.
Every surface of SERS substrates varies a little bit, and these variations change the SERS enhancement, therefore quantitative measurements are not very popular with this technique. However, some publications have written that you can combine SERS with Machine Learning to make SERS quantitative technique.
We deliver substrates approximately within one week plus the delivery time which depends on the destination country/region, but in Europe it is 1-2 days, outside Europe 3-4 days.
You can get free delivery for orders bigger then 900 € (after our standard discount)
We offer discounts for returning customers
