Synergies between ultrasound and aminated nanoparticles in the synthesis of DHP pharmaceuticals
Today, attentions to the synergistic effects have raised due to bringing convenience and expedition into the complex processes. In the field of catalysis, synergistic effects between the ultrasound waves (USWs) and the nanosized heterogeneous species is one
Imaging metal nanoparticle adsorption on graphene aerogels
The functionalization of porous carbon aerogels and sponge-like materials with metal nanoparticles (NPs) has shown significant promise for several applications, including energy storage and harvesting and environmental remediation. Methods for imaging the internal structure of these porous
Fullerene soot nanoparticles impose threat to glial cell community
Nanotechnology principally deals with engineering or fine tuning of functional matters at their molecular level. The field has generated an exciting scientific attention globally because of the innumerable possibilities it holds. Since it offers opportunities to mold
Green synthesized Ag/AgCl nanoparticles using Malva Sylvestris aqueous leaf extracts
Nanoparticles are molecular or atomic aggregations with a size range of 1-100 nm. Their physical and chemical properties are different from bulk materials with the same formula. They can be produced by chemical, physical and green methods;
Therapy of osteoporosis by the transdermal formulation based on raloxifene nanoparticles in ovariectomized rat
Osteoporosis results from insufficient post-menopausal estrogen levels and collapse of the balance between osteoclasts and osteoblasts, and the osteoporosis is a common systemic skeletal condition that is related to low bone mineral density and pathological fractures. The
Magnetic NPs for automatic speciation analysis of inorganic arsenic in environmental water samples
Arsenic is a ubiquitous element in the environment originated from natural sources as well as human activities. This element has been identified as a public health problem because it has serious toxic effects even at low exposure
Chemical reactions speed up with hollow fluorescent carbon and gold nanoparticles
Gold nanoparticles (Au NPs) constitute one of the most interesting model systems in the area of heterogeneous catalysis. Au NP hybrids with hollow nanocages, alloyed nanoparticles and core-shell structure play important roles in harvesting light energy and
Hidden toxicity of zinc oxide nanoparticles
Zinc Oxide (ZnO) is one of the most exploitable nanoparticles (NPs) in industrial and consumer products especially in cosmetics, food additives, pharmaceuticals, biosensors, photo electricity and rubber industry etc. Regarding their wide variety of applications, they constantly
Melatonin play wonders in Zinc oxide nanoparticle induced toxicity
Over the past several decades, the field of nanotechnology has perceived an uplifting graph of achievements and developments. Among the principal nanoparticles contributing for the same, ZnO nanoparticles should be considered as the foremost. By having unique
The road to new aortic valve disease treatment: Innovations in 3D models and drug delivery
Calcific Aortic Valve Disease (CAVD) resulting in aortic stenosis is a common heart disease that affects 25% of people over 65 years old, causing 17,000 deaths per year in the USA. The aortic valve regulates blood flow
A versatile in vitro bioassay for the screening of neurotrophic factor gene therapy systems to combat blindness
Glaucoma is the world’s second leading cause of blindness after cataracts, affecting about 80 million people worldwide annually. The disease is characterized by neurodegeneration involving a progressive visual field loss from the periphery towards the center, and
Behavior of Staphylococcus epidermidis in biosynthesis of silver and cadmium sulfide nanoparticles
Microorganism biosynthesizes nanoparticles using its enzymes and biomolecules which can act as reducing and capping agents. In fact, the nanoparticle is a produce of detoxification pathways. These pathways neutralize the toxicity of metal ions and trap them
Targeted nanoparticles for molecular imaging
Oncologic, cardiovascular, and neurological diseases are the most common causes of death in the developed world. It is well established, especially for cancer that early diagnosis results in more favorable outcomes. Although various diagnostic tests are available
Cultured macrophages help predict lung toxicity of inhaled nanoparticles
Many small particles of industrial or occupational origin are believed to infer an inflammatory or otherwise toxic potential to human health upon inhalation. Knowledge on this issue is especially important for the very small nanoparticles, which measure
Diamonds – The doctors’s best friend?!
Most people know about diamonds as jewelry and as the hardest material that can cut nearly everything. It is also known that what makes diamonds unique is the crystalline structure, which is brought about primarily with high
Enhanced absorption or transparency in hybrids of nanoparticles and graphene
The appealing side of nanotechnology lies in the fact that ordinary materials show surprising properties when their size is reduced to billionths of meters (nanometers). For example, we all know that silver is gray and gold is
Targeted ion therapy using nanoparticles – a new direction
A living body is made of the smallest building block, called ‘cell’. It gives us a shape, helps us to perform physiological and biological activities, and so on. A eukaryotic cell contains a nucleus, buried in the
Imaging of viruses with the help of surface plasmons
For a long time biosensors based on the surface plasmon resonance (SPR) phenomenon were not considered as effective tools to detect and visualize the binding of individual nano-scale objects to the functionalized sensor surface. However, innovative studies
How to design a plasmonic sensor more sensitive to the environment?
Noble metal nanoparticles (NPs) such as Au NPs and Ag NPs support localized surface plasmon resonances (LSPRs), which are the light-coupled coherent oscillations of free electrons confined within the NPs. The LSPRs, which are characterized by the
Using nanotechnology to outsmart pancreatic cancer
