Synthesis of acid-degradable Au NCs. SPDP-activated Au NPs were conjugated with acid-cleavable diaminoketal (DAK) cross-linkers. DAK cross-linker-conjugated Au NPs were then mixed with excess SPDP-activated Au NPs to form clusters. The resulting Au NCs were PEGylated by reaction of amino PEG with the NHS group available on the surface of SPDP-activated Au NCs
