Introduction to Molecular assembler
Many definitions are present for the molecular assemblers but the most famous and original is by Eric Drexler. According to him Molecular assemblers are the molecule machines, which have the capability of assembling the other molecules, energy, program instructions and small building blocks to process. These assemblers can work individually as a stand alone system and also with number of desktop systems. Difference exists sometimes between synthetic and naturally occurring molecular assemblers. These assemblers are just like the compliers or interpreters in terms of computer sciences.
How molecular assembler works
Molecular assemblers work with the molecules systematically, these assemblers or reassembles the molecules of a particular substance in a proper manner without leaving any empty position. For example in the ribosome, it first reads the required DNA and RNA strands from a cell and then assembles the fundamental protein molecules of a specific part. Molecular or nano assemblers have nano configuration in there architectures. Molecular assembly is the fundamental property of nanomachines.
All the hypothetical machine which has the ability to manipulate the individual atom is a molecular assembler. Most assembler architecture keep the source code hidden to the physical assembler. At every stage of a manufacturing process, that stage is read from an common computer executable file and then broadcast to all the assemblers. If any assembler gets out of range of that computer, or when the connection between that computer and the assembler is broken down the assembles stops replicating which is one of the major drawbacks of molecular assembler.some scientists
Molecular assembler construction
Molecular assemblers can be constructed by many processes but one the famous process for assembler construction is the evolutionary mimic process which are based on the typical mimic of biological molecular heart pump machine and kidney transplant robots are one of the biggest examples of the molecular assemblers.there are two types of assemblers which re used world wide
- Simple molecular assemblers
- Complex molecular assemblers
Simple molecular assemblers
Simple molecular assemblers requires no integration circuits in them.They have simple nano infra structure and are mostly used in the fields of medicine and chemistry.They function normally by assembling or re-assembling the molecules for obtaining the exact results.
Complex molecular assemblers
Complex molecular assemblers are quite different in their construction and architecture.They require integration,complex programming and module settings.Complex system does not work periodically and directly .You must need to start over from the first step for every functionality.When employed with the biological systems ,complex assembly of molecules came into being.Scientists have discovered they complex molecular assemblers are much safer than simple assemblers because its quite difficult to properly understand the complexity and infrastructure which makes it hard for the criminal and unauthorized bodies to access these machines.
Drawbacks of molecular assemblers.
- One of the drawback of nano molecular assembler is its molecular structure. Destructive properties of the materials can be discovered from the additional components that molecular assemblers process.
- Re programing is required for the specific products reproduction.By default molecular assemblers does not support self replication.
- Another important drawback of Molecular assemblers is their dependability. molecular machines are system dependent sometimes .They are not platform independent and can only support the task,function or program for which they are designed for.
- Molecular assemblers are some how efficient and accurate in telling the future reactions and results.But still chemical reactions,error rates,destruction rate cannot be predicted with full confidence.Some chances of wrong prediction and negative results are still their even with the most advanced forms of molecular assemblers.
- Molecular assemblers are quite expensive because they use nanotechnology in building their major infrastructure and functionality.Scientists and manufacturers have to invest heavy amounts for proper development of molecular products.
