Surfactor

Use Surfactor to estimate the absolute surface area of particles of arbitrary shape such as cells.

Before using this probe, you need to use Optical Fractionator (or another systematic random sampling scheme) to obtain a systematic random sample of particles.

 

Identifying where rays are emanating from the chosen point that is associated with each particle crosses the particle’s boundaries, and by adjusting tangential rays at these points the mean surface area of particles can be estimated.

All surfactor rays do not necessarily need to intersect the particle.

A ray might intersect a particle multiple times, depending on the shape of the particle and the location of the arbitrary point associated with the particle.
