Biosensors: Controlling Lipid Membrane Architecture for Tunable Nanoplasmonic Biosensing (Small 23/2014)

A biosensing platform is presented by N.-J. Cho and co-workers that utilizes plasmonic nanodisk sensors for detecting lipids and proteins. The image shows circular gold nanodisks deposited on a glass substrate, as directly observed by atomic force microscopy. On page 4828, the nanodisks appear as dark yellow spots and the glass substrate underneath is blue. The platform is suitable for the fabrication of different types of lipid membrane architecture, enabling tunable measurement responses. Platforms of this kind have strong potential for lab-on-a-chip and diagnostic applications.
