Polystyrene (PS) colloidal particles (10% w/w) with diameters of 100 and 500 nm were obtained from the Duke Scientific Corporation in Palo Alto, CA, USA. Anhydrous ethanol, Si wafers, hydrogen peroxide, ammonia, and sodium dodecyl sulfate were purchased from Sigma-Aldrich Co., Ltd., Beijing, China. The Ag (99.99%) target material was purchased from Beijing TIANQI Advanced Materials Co., Ltd., Beijing, China. AFP-L3 ELISA kits, phosphate-buffered saline solution (PBS; 0.01 M, pH = 7.4), and bovine serum albumin (BSA), were purchased from Beijing Dingguo Changsheng Biotechnology Co., Ltd., Beijing, China. 5,5′-Dithiobis (succinimidyl-2-nitrobenzoate) (DSNB) [15 (link)] and ultrapure water were used in the experiment.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
