Abstract Fluorescent cellular biomarkers play a prominent role in biosciences. Most of the available have some drawbacks due to either physical and optical or cytotoxic properties. In view this, we investigated potential green fluorescent nanodiamonds as living cells. Nanodiamonds were functionalized by attaching antibodies that target intracellular structures such actin filaments mitochondria. Then, nanodiamond conjugates transfected into HeLa Transfections mediated 4 th ‐generation...
Magnesium alloys are promising materials for bioresorbable implants that will improve patient life and reduce healthcare costs. However, their clinical use is prevented by the rapid degradation corrosion of magnesium, which leads to a fast loss mechanical strength formation by-products can trigger tissue inflammation. Here, tannic acid coating proposed control AZ31 AZ91 alloys, starting from previous study authors on AZ91. The coatings two were characterized both chemical (EDS, FTIR, XPS)...
Abstract We have developed a technique to manipulate bifunctional DNA molecules: One end is thiolated bind patterned gold surface and the other biotinylated microtubule gliding over kinesin‐coated surface. found that molecules can be stretched overstretched between pads motile microtubules, they form dynamic networks. This serves as proof‐of‐principle biological machineries used in vitro accomplish parallel formation of structured templates will applications biophysics nanoelectronics.
Microbiological photosynthesis is a promising tool for producing hydrogen in an ecologically friendly and economically efficient way. Certain microorganisms (e.g. algae bacteria) can produce using hydrogenase and/or nitrogenase enzymes. However, their natural capacity to relatively low. Thus, there need optimize core photosynthetic processes as well cultivation, more production. This review aims provide holistic overview of the recent technological research developments relating...
Nanodiamonds (NDs) are an emerging class of engineered nanomaterials that hold great promise for the next generation bionanotechnological products to be used drug and gene delivery, or bio-imaging biosensing.
