(A) Fresh porous Si particles in a droplet of 5% dextrose solution. Particle clumping is observed due to the hydrophobic nature of the unmodified porous Si particles. (B) Oxidised particles in a droplet of 5% dextrose solution. These particles were observed to be more dispersed in solution, presumably because of the hydrophilic nature of the SiO2 surface.
