Translation enhancement by AuNP-mPEG. a. Normalized peak fluorescence intensity of mCherry when AuNP (squares), AuNP-mPEG (reaction ratio 1:200, circles), AuNP-mPEG (1:1000, triangles), and AuNP-mPEG (1:2000, inverted triangles) are added. b. Repeated for eGFP translation. c. 1.5% agarose gel electrophoresis in 0.5× TBE at 3.8 V/cm for 1.5hrs. Lane 1: retic lysate kit mixture, Lane 2: AuNP, Lane 3: AuNP-mPEG (reaction ratio 1:200), Lane 4: AuNP-mPEG (1:1000), 5: AuNP- mPEG (1:2000), Lane 6: mixture of 1 & 2, Lane 7: 1 & 3, Lane 8: 1 & 4, and Lane 9: 1 & 5.
