In a timely way, it sets out a distinct quantum biology agenda. The burgeoning fields of nanotechnology, biotechnology, quantum technology, and quantum information processing are now strongly converging. The acronym BINS, for Bio-Info-Nano-Systems, has been coined to describe the synergetic interface of these several disciplines. The living cell is an information replicating and processing system that is replete with naturally-evolved nanomachines, which at some level require a quant 606 $aQuantum biochemistry 606 $aLife$zOrigin 615 0$aQuantum biochemistry. 615 0$aLife 676 $a576.8/3 701 $aAbbott$b Derek$f1960-$01506959 701 $aDavies$b P.
