Photographs of polyA (10, 20 and 30, respectively) DNA-functionalized AuNPs dispersed in various concentrations of organic solvents. DMF = dimethylformamide; DMSO = dimethyl sulfoxide; EG = ethylene glycol. Each sample also contained 5 mM HEPES, pH 7.4. (A) Photographs of polyA10-DNA-functionalized AuNPs dispersed in various concentrations of organic solvents. (B) Photographs of polyA20-DNA-functionalized AuNPs dispersed in various concentrations of organic solvents. (C) Photographs of polyA30-DNA-functionalized AuNPs dispersed in various concentrations of organic solvents.
