We constructed hierarchical complexes via the peptide-regulated assembly of porphyrin and Pt for converting light energy into chemical energy and storing it as NADH.

Our experiment tested which of five treatments kept Christmas trees (Pinus radiata) healthy for longest. The five different treatments were submerging the cut ends of pine branches in water (control), freshly boiled water (to potentially dissolve sap in cut stems), energy drink (to provide sugars), beer (to provide sugars and kill germs) or spraying the needles with hairspray (to reduce water loss). We measured how much light energy was converted to chemical energy by the needles, thus recording their health. The treatment that maintained the highest level of photosynthetic health was the hairspray, with an average of 90% of original needle health after 27 days. Branches in freshly boiled water and control treatments both retained ~68% of their original photosynthetic health. Branches in both beer and energy-drink treatments declined to about a third of their original needle health. In conclusion, we recommend spraying cut Pinus radiata Christmas trees with hairspray.

This article presents research work of various groups that are working on using nanotechnology in medical treatments. The researchers at Cornell University’s nanofabrication lab needed to make the propellers on the chip and harvest them, rather than rinse them off. After trial and error, the Cornell engineers came upon a workable combination of biochemical methods and fabrication. Mounting a 2-micrometer polystyrene sphere to the motor, the Cornell researchers made a mechanical amplifier to evaluate the motion of the FI-ATPase enzyme. The group made a small photosynthetic cell by installing the protein, bacteriorhodopsin, into liposomes. The protein converts light energy into chemical energy by synthesizing ATP. The ATP runs the motor and then gets recycled back to adenosine diphosphate in a closed chemical system. A nanotube bearing could provide frictionless rotation without wear.
