Applications of bionanotechnology are extremely widespread. Insofar as the distinction holds,<unk>  is much more commonplace in that it simply provides more tools for the study of biology. Bionanotechnology, on the other hand, promises to recreate biological mechanisms and pathways in a form that is useful in other ways. Nanomedicine Nanomedicine is a field of medical science whose applications are increasing. ;Nanobots The field includes nanorobots and biological machines, which constitute a very useful tool to develop this area of knowledge. In the past years, researchers have made many improvements in the different devices and systems required to develop functional nanorobots – such as motion and magnetic guidance. This supposes a new way of treating and dealing with diseases such as cancer; thanks to nanorobots, side effects of chemotherapy could get controlled, reduced and even eliminated, so some years from now, cancer patients could be offered an alternative to treat such diseases instead of chemotherapy, which causes secondary effects such as hair loss, fatigue or nausea killing not only cancerous cells but also the healthy ones. Nanobots could be used for various therapies, surgery, diagnosis, and medical imaging – such as via targeted drug-delivery to the brain (similar to nanoparticles) and other sites. Programmability for combinations of features such as "tissue penetration, site-targeting, stimuli responsiveness, and cargo-loading" makes such nanobots promising candidates for "precision medicine". At a clinical level, cancer treatment with nanomedicine would consist of the supply of nanorobots to the patient through an injection that will search for cancerous cells while leaving the healthy ones untouched. Patients that are treated through nanomedicine would thereby not notice the presence of these nanomachines inside them; the only thing that would be noticeable is the progressive improvement of their health.<unk>  may be useful for medicine formulation. "Precision antibiotics" has been proposed to make use of bacteriocin-mechanisms for targeted antibiotics. ;Nanoparticles Nanoparticles are already widely used in medicine. Its applications overlap with those of nanobots and in some cases it may be difficult to distinguish between them. They can be used to for diagnosis and targeted drug delivery, encapsulating medicine. Some can be manipulated using magnetic fields and, for example, experimentally, remote-controlled hormone release has been achieved this way. On example advanced application under development are "Trojan horse" designer-nanoparticles that makes blood cells eat away – from the inside out – portions of atherosclerotic plaque that cause heart attacks and are the current most common cause of death globally. ;Artificial cells Artificial cells such as synthetic red blood cells that have all or many of the natural cells' known broad natural properties and abilities could be used to load functional cargos such as hemoglobin, drugs, magnetic nanoparticles, and ATP biosensors which may enable additional non-native functionalities. ;Other Nanofibers that mimic the matrix around cells and contain molecules that were engineered to wiggle was shown to be a potential therapy for spinal cord injury in mice. Technically, gene therapy can also be considered to be a form of<unk>  or to move towards it. An example of an area of genome editing related developments that is more clearly<unk>  than more conventional gene therapies, is synthetic fabrication of functional materials in tissues. Researcher made C. elegans worms synthesize, fabricate, and assemble bioelectronic materials in its brain cells. They enabled modulation of membrane properties in specific neuron populations and manipulation of behavior in the living animals which might be useful in the study and treatments for diseases such as multiple sclerosis in specific and demonstrates the viability of such synthetic in vivo fabrication. Moreover, such genetically modified neurons may enable connecting external components – such as prosthetic limbs – to nerves. Nanosensors based on e.g. nanotubes, nanowires, cantilevers, or atomic force microscopy could be applied to diagnostic devices/sensors<unk> <unk>  (sometimes referred to as nanobiology) may be best described as helping modern medicine progress from treating symptoms to generating cures and regenerating biological tissues. Three American patients have received whole cultured bladders with the help of doctors who use nanobiology techniques in their practice. Also, it has been demonstrated in animal studies that a uterus can be grown outside the body and then placed in the body in order to produce a baby. Stem cell treatments have been used to fix diseases that are found in the human heart and are in clinical trials in the United States. There is also funding for research into allowing people to have new limbs without having to resort to prosthesis. Artificial proteins might also become available to manufacture without the need for harsh chemicals and expensive machines. It has even been surmised that by the year 2055, computers may be made out of biochemicals and organic salts. Another example of current<unk> cal research involves nanospheres coated with fluorescent polymers. Researchers are seeking to design polymers whose fluorescence is quenched when they encounter specific molecules. Different polymers would detect different metabolites. The polymer-coated spheres could become part of new biological assays, and the technology might someday lead to particles which could be introduced into the human body to track down metabolites associated with tumors and other health problems. Another example, from a different perspective, would be evaluation and therapy at the nanoscopic level, i.e. the treatment of nanobacteria (25-200 nm sized) as is done by NanoBiotech Pharma. "Nanoantennas" made out of DNA – a novel type of nano-scale optical antenna – can be attached to proteins and produce a signal via fluorescence when these perform their biological functions, in particular for their distinct conformational changes. This could be used for further<unk>  such as various types of nanomachines, to develop new drugs, for bioresearch and for new avenues in biochemistry. While nanobiology is in its infancy, there are a lot of promising methods that will rely on nanobiology in the future. Biological systems are inherently nano in scale; nanoscience must merge with biology in order to deliver biomacromolecules and molecular machines that are similar to nature. Controlling and mimicking the devices and processes that are constructed from molecules is a tremendous challenge to face for the converging disciplines of<unk> . All living things, including humans, can be considered to be nanofoundries. Natural evolution has optimized the "natural" form of nanobiology over millions of years. In the 21st century, humans have developed the technology to artificially tap into nanobiology. This process is best described as "organic merging with synthetic". Colonies of live neurons can live together on a biochip device; according to research from Dr. Gunther Gross at the University of North Texas. Self-assembling nanotubes have the ability to be used as a structural system. They would be composed together with rhodopsins; which would facilitate the optical computing process and help with the storage of biological materials. DNA (as the software for all living things) can be used as a structural proteomic system – a logical component for molecular computing. Ned Seeman – a researcher at New York University – along with other researchers are currently researching concepts that are similar to each other. Bionanotechnology DNA nanotechnology is one important example of bionanotechnology. The utilization of the inherent properties of nucleic acids like DNA to create useful materials or devices – such as biosensors – is a promising area of modern research. Another important area of research involves taking advantage of membrane properties to generate synthetic membranes. Proteins that self-assemble to generate functional materials could be used as a novel approach for the large-scale production of programmable nanomaterials. One example is the development of amyloids found in bacterial biofilms as engineered nanomaterials that can be programmed genetically to have different properties. Protein folding studies provide a third important avenue of research, but one that has been largely inhibited by our inability to predict protein folding with a sufficiently high degree of accuracy. Given the myriad uses that biological systems have for proteins, though, research into understanding protein folding is of high importance and could prove fruitful for bionanotechnology in the future. DNA digital data storage refers mostly to the use of synthesized but otherwise conventional strands of DNA to store digital data, which could be useful for e.g. high-density long-term data storage that isn't accessed and written to frequently as an alternative to 5D optical data storage or for use in combination with other<unk> . Lipid nanotechnology is another major area of research in bionanotechnology, where physico-chemical properties of lipids such as their antifouling and self-assembly is exploited to build nanodevices with applications in medicine and engineering. Lipid nanotechnology approaches can also be used to develop next-generation emulsion methods to maximize both absorption of fat-soluble nutrients and the ability to incorporate them into popular beverages. "Memristors" fabricated from protein nanowires of the bacterium Geobacter sulfurreducens which function at substantially lower voltages than previously described ones may allow the construction of artificial neurons which function at voltages of biological action potentials. The nanowires have a range of advantages over silicon nanowires and the memristors may be used to directly process biosensing signals, for neuromorphic computing (see also: wetware computer)
