Particle composition study. (a) Penta-functional particles made from monomer solutions containing 15 - 35% PEG-DA were investigated for probe incorporation (b) and hybridization signal using two methods of fluorescent detection (c, d). The error bars shown in (b) represent the standard deviation over three measurements. In (c) and (d), fluorescent scans along the particles were normalized to the intensity measured for the 15% PEG-DA regions in order to show penetration trends for the two labeling schemes. Particles have dimensions of 400 × 100 × 30 μm.
