tfw1, I use a capping agent for several reasons. One, it helps prevent the aggregation of the silver nanoparticles into larger, less effective or non effective particles, two it helps keep the batch stable and three it helps the AgNPs to make it through the rigors of the stomach intact. I suspect it also helps extend the useable life of the silver when you are dealing with higher ppm batches. There are many different capping agents and some are more effective than others.
When you look at studies using silver nanoparticles, they mostly use a capping agent of some type.
