Hi! Welcome to OA!
The femtotech question is an interesting one. Magmatter (which is currently likely to undergo a mild revision in the relatively near future) does operate on the femtoscale, so can fulfil some of the properties predicetd by Hugo de Garis for femtotech. However magmatter has many physical limitations, not least its tendency to collapse into a black hole. So we tend to avoid the term femtotechnology, and use magmatter tech instead.
