Surface Plasmon Resonance Database (SPRD) is created by collecting technical details from Materials and Methods sections of peer reviewed publications. The goal of SPRD is to assist users of SPR technology with future experimental planning and optimization processes. SPRD will be most effective with critical review and contributions of the scientific community. We strongly encourage all users to send us additional manuscript entries and suggestions on existing data to correct mistakes or fill in missing information. SPRD does not include all existing manuscripts with SPR data.
