Nanocomposites based on Self-assembly of Collagen with DNA
Collagen is a fibrous protein that undergoes a complex self-organizing process at the nano-, micro-, and macro-scales to form hierarchical fibers. Fiber nano/microstructures are extremely sensitive to biophysical/biochemical environments. Their mechanical properties and anisotropy (macroscale) [...]
Identification of Dynamic Structural Domains in Proteins, Analysis of Local Bond Flexibility,and Application for Interpretation of NMR Experiments
A novel theoretical methodology is introduced to cidentify dynamic structural domains and analyze local flexibility in proteins. The methodology employs a multiscale approach combining identification of essential collective coordinates based on the covariance analysis of [...]
Intracellular Inclusions and Nanocrystals of magnetotactic coccus isolated from estuary in Colombia
Grisales S., Morillo V., Marquez M., Morales A., Salazar A., Universidad Nacional de Colombia Sede Medellín, CO
Magnetotactic bacteria containing intracellular membrane-bound nanocrystals of magnetite or greigite (Bazylinski, et al. 2004; Flies, et al. 2005). The bacteria may also have intracellular inclusions (Keim, et al. 2005). Magnetosome formation in magnetotactic bacteria provides [...]
Antibacterial activity of flame-made Ag/SiO2 nanoparticles
The synthesis of flame made Ag/SiO2 nanoparticles was achieved by flame spray pyrolysis. The precursor selection influence on the final product was studied. The produced powders were characterized by TEM/STEM, XRD, BET, UV/vis. Additionally, the [...]
Colloidal apatite nanoparticles exhibiting luminescence and magnetic susceptibility
Hydroxyapatite (HA) has been recognized for some time as a potential candidate for engineering hard-tissue replacements and drug and gene delivery systems. However, the inability to collidally disperse nano-HA (nHA), and perhaps create primary nHA [...]
Application of anatase TiO2 sol derived from peroxotitannic acid in crop plant diseases control and growth regulation
Synthetic germicides have been widely used to control crop diseases. But they caused many problems such as environmental pollution and food safety issues. It has consequently become necessary to develop alternative methods for the control [...]
Incorporation of Nanoparticles into Soy-based Polyurethane Foam
Nanotechnology is one of the most effective ways to develop advanced materials. Nanophases including nanoclay, Polyhedral Oligomeric Silsequioxane (POSS), organic and inorganic nanofibers are often used to be incorporated into polymer resin systems to improve [...]
Thermoresponsive Magnetic Micelles for Simultaneous Magnetic Hyperthermia and Drug Delivery
Hyperthermia has been shown to be a potentially effective therapeutic modality in cancer treatment as it intensifies the efficacy of chemotherapy. The hyperthermia has a good synergic effect with chemotherapy. Their sensitivity to chemotherapy after [...]
