The nanotech boost is located in the last room of the level and can be seen easily from the starting point of the glider run. To reach it, you need to use the glider and execute a U-turn at some point. You can achieve that in the very last section, before the landing area by going to the far right to give you enough space to turn around. After that you will need to go all the way back to get the boost.
