Gold nanoparticle-mediated signal amplification of liquid crystal biosensors for dopamineElectronic supplementary information (ESI) available. See DOI: 10.1039/c8an02171f

A unique design strategy was developed for the detection of dopamine using a newly synthesized amphiphile containing boronic acid head group at the aqueous-liquid crystal (LC) interface. The optical signal of LC for the detection of dopamine was highly amplified in the presence of functionalized gold nanoparticles. A new design was developed for detection of dopamine using a boronic acid based amphiphile at aqueous-liquid crystal interface. The detection was highly enhanced in presence of gold nanoparticles.
