A second major feature of SUPRASs
is the high concentration of amphiphiles they contain; typically between
0.1 and 1 mg lL1. This characteristic results in a high number
of binding sites for analytes and permits to achieve high
extraction efficiencies using low extractant volumes, which is requisite
in microextractions. Additional interesting properties for
extractions include non-volatility and non-flammability, which
permits the implementation of safer processes, and the use of
self-assembly based synthetic procedures that are within everyone’s
reach
