pH‐Sensitive Nanocomposites Using Polymer‐Coated Gold Nanorods
Source abstract
Abstract
This study investigates the synthesis of pH‐responsive, reversible nanocomposites comprising polystyrene sulfonate (PSS)‐coated gold nanorods and poly(allylamine hydrochloride) (PAH)‐coated gold nanorods, along with their optical properties. We observed a pH‐dependent swelling/shrinking of the nanocomposites and a dramatic redshift (∼60 nm) of the surface plasmon resonance (SPR) peaks as the pH changed from around 5.4 to 7.2 due to the increased side‐by‐side interactions of adjacent gold nanorods. These pH‐responsive nanocomposites, with tunable SPR peaks, hold potential for use as contrast agents in optical molecular imaging.
