Asymmetric functionalization of gold nanoparticles with oligonucleotides.
نویسندگان
چکیده
Gold nanoparticles (AuNPs) were anisotropically functionalized with two different oligonucleotide sequences using magnetic microparticles as geometric restriction templates for site-selective enzymatic extension of particle-bound oligonucleotides. The divalent linking capability of the resulting AuNPs allowed for the design and programmable assembly of discrete nanoparticle heterostructures.

Oligonucleotide gold nanoparticle conjugates are being used as diagnostic tools and gene silencing experiments. Thiol-chemistry is mostly used to functionalize gold nanoparticles with oligonucleotides and to incorporate DNA or RNA molecules onto gold surfaces. However, the stability of such nucleic acid-gold nanoparticle conjugates in certain conditions may be a limitation due to premature brea...

Synthesis and characterization of two functionalized gold nanoparticles by using of two poly functional amino acids (L-Arginine and L-Aspartic acid) are reported. The gold nanoparticles were reduced by sodium citrate and functionalized with L-Arginine at the pH of 7 and 11 and L-Aspartic acid at the pH of 7. Transmission electron microscopy, UV-Vis spectroscopy, dynamic light scattering, zeta p...

متن کاملColorimetric detection of DNA sequences based on electrostatic interactions with unmodified gold nanoparticles.
We find that single- and double-stranded oligonucleotides have different propensities to adsorb on gold nanoparticles in colloidal solution. We use this observation to design a hybridization assay based on color changes associated with gold aggregation. Because the underlying adsorption mechanism is electrostatic, no covalent functionalization of the gold, the probe, or the target DNA is requir...
متن کاملHigh performance liquid chromatographic analysis of reduction products of a thiolated DNA for immobilization on gold nanoparticles
DNA-based nano-biosensors are emerging scope in the field of biosensors. Many synthetic single stranded functional DNAs have been applied for development of such sensors, recently. Immobilization of DNA oligonucleotides on the surface of gold nanoparticles is a key step in the development of most colorimetric nano-biosensors. The bound DNA is usually thiolated and forms Au-S covalent bond to th...
