The quantification of nano- and microparticles is critical for diverse applications relying on the exact knowledge of the particle concentration. Although many techniques are available for counting particles, there are some limitations in regards to counting with low-scattering materials and facile counting in harsh organic solvents. Herein, we introduce an easy and rapid particle counting technique, termed "immobilized particle imaging" (IPI), to quantify fluorescent particles with different compositions (i.e., inorganic or organic), structures (i.e., solid, porous, or hollow), and sizes (50-1000 nm) dispersed in either aqueous or organic solutions. IPI is achieved by immobilizing particles..View full abstract
