A novel surface plasmon resonance (SPR) sensor system using a smartphone based on the metal nanoshell array sensing method is proposed and developed. The micro-flow injection method was used to prepare two-dimensional colloidal microsphere template. the metal nanoshell array was fabricated by combining the microsphere template and the magnetron sputtering technology. A smartphone and ... https://lockdownsecuritycanada.shop/product-category/ferrule-crimper/
