How'd you translate " reduce the Au3+ into nanoprisms" in the following?


Triangular gold nanoprisms (Fig. 13.13A) can be synthesised biologically24 in high yield at room
temperature by the reduction of aqueous chloroaurate ions (AuCl4–) by the extract of the plant lemongrass
(Cymbopogon flexuosus). During the reaction, a visible colour change from pale yellow to a ruby red,
indicating formation of gold nanoparticles. The reducing sugars (aldoses) present inside the lemongrass
extract were found to reduce the Au3+ into nanoprisms. By simple variation in the concentration of the
lemongrass extract in the reaction medium, it is possible to vary the size of the nanoprisms25 thereby the
longitudinal SPR band in NIR region can be easily tuned (Fig. 13.13B).
