Hi All,
I would like to purchase a range of fluorescent polystyrene nanoparticles that are quite monodisperse (narrow size distribution) and all within the nano size range. They are for immune cell experiments.
Most companies appear to produce particle preps of broad size ranges.
Many thanks,
Josh
Bangs lab is pretty good for this.

Thanks Michael, Hugh and Pierre. Appreciate your suggestions.
However, we're after a range of sub-micron nanoparticles...
Thanks in advance
Please be specific by what you mean by submicron. The reference I sent you is 50nm in diameter. You won't find much smaller than that (20nm is the smallest I have ever heard of, but then you have to functionalize the bead yourself with fluorophores). Another option is to use quantum dots.
I'm not really sure what application you want the beads for? Do they need to be made of polystyrene? I would recommend Tetraspeck beads. They are a good standard for fluorescent microsopes, which is what I'm assuming you need them for.
