HVAC Control in the New MillenniumAdvanced assemblers will be able to do more than existing proteinmachines. They will be programmable like ribosomes, but they will beable to use a wider range of tools. They will be made of materials thatare stronger and more stable than proteins. They will be able to rotateand move molecules in three dimensions under programmed control,making possible the precise assembly of complex objects.DisassemblersMolecular tools will be able to take anything apart, a few atoms ata time. A nanomachine could also apply mechanical force, pryinggroups of atoms free. A nanomachine that is able to do this, while recordingwhat it removes layer by layer, is a disassembler.Assemblers can be used to synthesize things while disassemblerscan help to analyze things. Assemblers require the ability of enzymesand chemical reactions to form bonds and of machines to control theprocess.Disassemblers require the ability of enzymes and chemical reactionsto break bonds and of machines to control the process. Enzymes,acids, oxidizers, alkali metals, ions, and reactive groups of atoms calledfree radicals can break bonds and remove groups of atoms.Future NanotechnologyAs nanotechnology moves beyond proteins, molecules will be assembledlike components. Molecular tools will bond molecules togetherto make tiny gears, motors, levers, and casings, and assemble them tomake complex machines.One type of virus acts like a spring-loaded syringe and can injectviral DNA. This DNA then directs the cell’s machines to build more viralDNA and syringes.Parts containing only a few atoms will be lumpy, but they canwork if they have smooth bearings to support them. Some bonds betweenatoms make excellent bearings. A part can be mounted by meansof a single chemical bond that will let it turn freely and smoothly. Abearing can be made using only two atoms and moving parts need haveonly a few atoms.©2001 by The Fairmont Press, Inc. All rights reserved.
