Microscopic EthicsBy: Matthew SparksHistory
In 1959, Richard Feynman proposed an idea that we could manipulate things as small as atoms or molecules, we just do not have the ability to do so yet.Said we should be able to create machines that can arrange or rearrange atoms and molecules however we wantHow small can we go?Since the 1970s, computers and their components have decreased in size at least every 6 months
What is Nanotechnology?Improvement of all human biological systems from the molecular levelPreserving and improving human health using molecular toolsEmployment of molecular machine systems to address medical problems
Uses in Medical FieldsBiotechnology
BiotechnologyThe application of the principles and practices of engineering and technology to the life sciences
Limiting and delivering stem cells
SurgeryAbsolute noninvasive surgery
No risk of scars or outside influence
Doctor never even has to actually touch the patient
Construct new, or repair organs from the insideSurgery cont.Some nanomachines used as white blood cells
Viruses and bacteria cannot develop any kind of immunity
DrugsCan be administered through a regular syringe
Thousands can be administered at one time, for one, or many treatments
Can construct, or deconstruct molecules to treat, or destroy
DiagnosticsDiagnostic nanobots can take measurements, track certain cells, bacteria, etc.Transmit data back to doctorsNanocameras take images of healthy and/or damaged cellsCan determine if other nanobots present should actMedical RobotsCan be effective in almost any part of human body
Directed targeting of infected or diseased areasEthical IssuesNot enough extensive work yet
Nanobots may be so small they can pass through membranes within the body
Not known if nanobots toxic to humansIssues cont.Long term risks
Invisible tracking and recording devices
BioterrorismIssues cont.How much will it cost?
Separation of those who can afford nanomedicine and who cannot?
Altering DNA in unborn childrenTranshumanismTransition from normal human, to one with enhanced abilities due to genetic enhancements
Next step in human evolution?
Longer life spans overpopulation
Eliminate disease, but eliminating humanity?
And in ConclusionOverall positive benefits would help humans in eliminating disease and better health
Negatives could be catastrophic, not only to oneself, but to the world
What do you think?Better for humanity, or a downfall?Would there still be a distinction between man and machine? Or another category?Could nanotechnology be controlled to only pertain to the good aspects?Who should be the ones that receive the nanomedicinal treatments?ReferencesBerger, M. (2008, January 9).
