Abstract
While bio(organic-inorganic) compatibility and absence of cytotoxicity are crucial to create a successful nanocarrier for applications in biosensing and drug delivery [1], the study of its stability before commercialization is quite important. In the present work, the stability of gold nanoparticles (AuNPs) functionalized with L-Cysteine (Cys) and Cysteine-Glycine (Cys-Gly) was studied. The AuNPs surface modification with Cys and CysGly was performed to improve their biocompatibility [2] and, after that, the stability of capped AuNPs was investigated. The synthetized AuNPs using 10 μM of cysteine and 20 μM of Cys demonstrated stability after 1 month of storage, while all other concentration ratios resulted in the formation of chain-like conglomerates. For AuNP capped with CysGly all modifier concentrations led to stable samples within 1 month of storage.
