This results in delays in emergency situations. The storage time using standard method is only about 42 days. Red blood cells cannot be sterilized to remove infective agents like hepatitis viruses, H.I.V. and other potential emerging infective agents. Thus, red blood cells substitutes are being developed. Red blood cell (rbc) contains Hb, antioxidant enzymes and multienzyme system to prevent the conversion of Hb into nonfunctioning metHb. First generation rbc substitute is just an oxygen carrier based on the use of modified Hb without the presence of rbc enzymes or rbc membrane. Second generation rbc substitute is more than an oxygen carrier, it is the use of modified Hb containing rbc antioxidant enzymes. Third generation rbc blood substitute is closer to rbc, as it contains Hb and all the enzymes of rbc and the rbc membrane is replaced with synthetic membrane. Semi-synthetic DNA–protein conjugates: novel tools in analytics and nanobiotechnology Abstract This article reports on the syntheses, characterization and applications of semi-synthetic conjugates composed of nucleic acids, proteins and inorganic nanoparticles. For example, self-assembled oligomeric networks consisting of streptavidin and double-stranded DNA are applicable as reagents in immunoassays, model systems for ion-switchable nanoparticle networks as well as nanometer-scaled ‘soft material’ standards for scanning probe microscopy. Covalent conjugates of single-stranded DNA and streptavidin are utilized as biomolecular adapters for the immobilization of biotinylated macromolecules at solid substrates via nucleic acid hybridization. This ‘DNA-directed immobilization’ allows for reversible and site-selective functionalizationofsolidsubstrateswithmetalandsemiconductornanoparticlesor,viceversa,fortheDNA- directed functionalization of gold nanoparticles with proteins, such as immunoglobulins and enzymes. This approach is applicable for the detection of chip-immobilized antigens. Moreover, covalent DNA–protein conjugates allow for their selective positioning along single-stranded nucleic acids, and thus for the construction of nanometre-scale assemblies composed of proteins and/or nanoclusters. Examples include the fabrication of functional biometallic nanostructures from gold nanoparticles and antibodies, applicable as diagnostic tools in bioanalytics. Converging science and technology at the nanoscale: opportunities for education and training The Impact of Nanobiotechnology on the Development of New Drug Delivery Systems Full free Pdf Abstract: Nanotechnology, or systems/devices manufactured at the molecular level, is a multidisciplinary scientific field undergoing explosive development. A part of this field is the development of nanoscaled drug delivery devices. Nanoparticles have been developed as an important strategy to deliver conventional drugs, recombinant proteins, vaccines and more recently nucleotides. Nanoparticles and other colloidal drug delivery systems modify the kinetics, body distribution and drug release of an associated drug. Other effects are tissue or cell specific targeting of drugs and the reduction of unwanted side effects by a controlled release. Therefore nanoparticles in the pharmaceutical biotechnology sector improve the therapeutic index and provide solutions for future delivery problems for new classes of so called biotech drugs including recombinant proteins and oligonucleotides. This review discusses nanoparticular drug carrier systems with the exception of liposomes used today, and what the potential and limitations of nanoparticles in the field of pharmaceutical biotechnology are. Bio-Nano/Microtechnology Workshop Report Christopher Chen, University of Pennsylvania Rebekah Drezek, Rice University Jennifer West, Rice University Summary Two workshops on nanoscale and microscale biological phenomena were held at the 2005 Whitaker Summit meeting. Three primary topics were discussed in each workshop. These topics are summarized below and then elaborated upon in the sections which follow. First, it is clearly evident that research in the area of bionano- and microtechnology is rapidly expanding with potential applications to diverse areas of biomedical engineering spanning from biomaterials to molecular imaging to targeted therapeutics. Although the importance of nano and microtechnology to the future of bioengineering is clear, it is far less obvious how to optimally integrate concepts required to developing a fundamental understanding of these new areas into existing curricula at the undergraduate and graduate levels. Should new tracks in micro/nanobiotechnology be created? Alternatively, should information be integrated into existing undergraduate courses? If so, which courses and what material? Second and very closely related to this first question, when in the bioengineering curriculum should the relevant information be covered? Is the material appropriate for early undergraduate education or should micro/nano courses be predominantly graduate level offerings? Third, in this area in particular, there is a definite need for hands-on experiential learning. How can this learning be accomplished in the presently cost-constrained environment of almost all universities and in particular, at institutions which do not have extensive laboratory facilities in these new areas? Finally, in addition to these questions specific to micro- and nanobiotechnology, two other topics more generally relevant to biomedical engineering education were discussed in the workshops. These included both the significant need for a central and lasting web location bioengineering departments could use to share developed modules and the need for a discipline-wide conversation on the costs and benefits of ABET accreditation to bioengineering. Nanobiotechnology Food, Health, and Nutrition Security Summary of the Chennai Dialogue, India, March 11–13, 2005 Organized by the International Food Policy Research Institute, the M.S. Swaminathan Research Foundation, and the XV Genetic Congress Trust. Nanobiotechnology: the promise and reality of new approaches to molecular recognition Nanobiotechnology is the convergence of engineering and molecular biology that is leading to a new class of multifunctional devices and systems for biological and chemical analysis with better sensitivity and specificity and a higher rate of recognition. Nano-objects with important analytical applications include nanotubes, nanochannels, nanoparticles, nanopores and nanocapa- citors.Here,we take a criticallookatthesubsetofrecent developments in this area relevant to molecular recog- nition. Potential benefits of using nano-objects (nano- tubes, quantum dots, nanorods and nanoprisms) and nanodevices (nanocapacitors, nanopores and nanocan- tilevers) leading to an expanded range of label multi- plexing are described along with potential applications in future diagnostics. We also speculate on further pathways in nanotechnology development and the emergence of order in this somewhat chaotic, yet promising, new field. Protein-protein Interactions as Target for New Therapeutic Molecules Major human diseases are caused or are associated with disturbances of compartmental- ised cyclic adenosine monophosphate (cAMP) signalling networks. The participants of the European research project “thera-cAMP” aim to identify lead compounds, which specifi- cally modulate protein-protein interactions in such signalling cascades. The approach could lead to alternative strategies for the treatment for diseases that are currently not addressed effectively by conventional pharmacotherapy. Toxic Substances Control Act and Engineered Nanoscale Substances There is considerable attention these days focused on the implications of engineered nanoscale materials. Governments worldwide are urged to get the policy and regulatory framework ‘right’ to enable nanotechnology to realise its full societal value, while at the same time effectively addressing health and environmental issues posed by nanotechnology. In the US, the Toxic Substances Control Act (TSCA) is the law that regulates new and existing chemical substances and provides a regulatory framework to address chemicals throughout their production, use and disposal. Bioprocessing & Biopartnering 2006 Featuring NanoBiotechnology Many people regard nanotechnology as a ‘stand- alone’ technology. While the technology itself is of great interest, the most intriguing aspect of nanotechnology is that it is increasingly being utilised as an integral part of a more complicated convergence matrix. The intersection of nanotechnology, biotechnology, information technology, and cognitive science, otherwise referred to as ‘NBIC convergence’, is leading to the development of nanobiotechnology products that promise to change radically the provision of healthcare in the decades ahead. Use of Magnetic Nanoparticles to Visualize Threadlike Structures Inside Lymphatic Vessels of Rats A novel application of fluorescent magnetic nanoparticles was made to visualize a new tissue which had not been detectable by using simple stereomicroscopes. This unfamiliar threadlike structure inside the lymphatic vessels of rats was demonstrated in vivo by injecting nanoparticles into lymph nodes and applying magnetic fields on the collecting lymph vessels so that the nanoparticles were taken up by the threadlike structures. Confocal laser scanning microscope images of cryosectioned specimens exhibited that the nanoparticles were absorbed more strongly by the threadlike structure than by the lymphatic vessels. Further examination using a transmission electron microscope revealed that the nanoparticles had been captured between the reticular fibers in the extracellular matrix of the threadlike structures. The emerging technology of nanoparticles not only allows the extremely elusive threadlike structures to be visualized but also is expected to provide a magnetically controllable means to investigate their physiological functions.
