Nanoparticle Diameter: 7 nm Oligo Length: Long (60-90 bases) PEG: 1 kDa Volume (@ 10 OD): 3 mL Gold nanoparticles functionalized with double-stranded DNA oligonucleotides. The sense strand is covalently attached to the nanoparticle surface through a thiol bond. It can be attached either through their 5' or 3' end. The antisense strand is loaded onto the particle by hybridizing to the sense strand. Oligonucleotides can be chosen to be between 11 and 90 bases long. For nucleotides of 59 bases and below, please choose "Short" option in the Oligo Length drop down box. For nucleotides between 60 and 90 bases please choose "Long" option. Please provide the sequence of the sense oligonucleotide that will be covalently attached to the surface in the box below. In the sequence please indicate the location of the thiol (SH) group. For example, the following sequence would be adsorbed through it's 5' end: " 5'--SH-ACGCGATTCGACCCTGACGATTGGC--3' "
