Gold Nanoparticle Specifications

Each batch of BBI gold nanoparticles are manufactured to our exacting standards using quality controlled manufacturing and testing procedures. The table below outlines the specifications of each different particle size must meet to ensure that we offer the highest specification particles on the market. Each batch is tested by at least two operators to ensure quality and batch to batch reproducibility is maintained.
