“…[5][6][7][8] Recently, both single-walled carbon nanotubes 9 and graphene oxide 10 have found their significant application for fluorescenceenhanced DNA detection. Till now, many other structures have been used in this assay, including silver nanoparticles, 11 multiwalled carbon nanotubes and single-walled carbon nanohorns, 12 carbon nanoparticles, 13 carbon nanospheres, 14 nano-C 60 , 15 mesoporous carbon microparticles, 16 poly(p-phenylenediamine) nanobelts, 17 polyaniline nanofibres, 18 poly(o-phenylenediamine) colloids, 19 poly(m-phenylenediamine) nanorods, 20 poly(2,3-diaminonaphthalene) microspheres, 21 coordination polymer colloids, nanobelts and microdendrites, [22][23][24][25] Ag@poly(m-phenylenediamine) core-shell nanoparticles, 26 tetracyanoquinodimethane nanoparticles, 27 supramolecular microparticles, 28 and porphyrin nanoparticles. 29 Polystyrene (PS) colloids are important in many areas of technology, such as paints, coatings, ceramics processing, and the construction of photonic bandgap crystals.…”
