    • Caution! Piranha solutions are extraordinarily dangerous, reacting explosively with trace quantities of organics. They should be handled in very small quantities with the utmost care.

    • 45 According to this model, p = r exp[-E/kT], where r accounts for the fact that all particle-surface collisions may not result in binding (i.e. a particle in solution may collide with another surface-bound particle rather than a region of organosilane), k is Boltzmann's constant, T is temperature in degrees K, and E is the energy barrier to binding. While colloidal Au represents only 30% of the total surface area, the percentage of non-contact sites available for 15-nm particles is far less than 70%. Thus r decreases with increasing coverage (at t = 0, r = 1; at longer times, r ≈ 0). While at low coverages (p ≈ 1 (≈r)) E must necessarily be quite small, it is likely that at higher coverages, the activation energy for particle binding increases due to interparticle repulsion. Surface coating does proceed more rapidly at 70 °C than at 20 °C (supporting information), but decreased viscosity and increased temperature account for most of this change.
