Over the past few years, nanoparticles have been widely used in therapeutic applications. It is well acknowledged that nanoparticles have improved the shortcomings of conventional treatments. The advantages and drawbacks of inorganic nanocarriers such as metal nanoparticles and quantum dots have been extensively studied. Although carbon nanotubes have been touted as a prominent medication delivery method, their phy Read More

Surface-enhanced Raman Scattering (SERS) is a sensing method based on inelastic scattering of a laser beam by a reporter molecule absorbed on a plasmonic substrate. The incident laser beam induces a localized-surface plasmon resonance in the substrate, which generates an oscillating electromagnetic field on the substrate dielectric surface. Under the influence of this field, the reporter molecule absorbed on the plasm Read More

Background: The insatiable need for low-power and high-performance integrated circuit (IC) results in the development of alternative options for metal oxide semiconductor field effect transistor (MOSFET) in the ultra-nanoscale regime. The practical challenge of the device scaling limits the use of MOSFET for future technology nodes. ICs are equipped with billions of transistors whose size must be scaled while increasing perf Read More

For the treatment of brain illnesses, there is growing interest in nose-to-brain drug administration. Other, more traditional methods of crossing the blood–brain barrier (BBB) are ineffective. As a result, the therapeutic concentration in the brain cannot be achieved, and the reaction is inadequate. Intranasal medication delivery is one intriguing technique for avoiding first-pass metabolism and bypassing the blood-brain barrier. It low Read More

Nanoparticles are well-established carriers for targeted delivery of bioactive polymeric nanoparticles (PNPs). They have attracted significant attention from pharmaceutical scientists globally due to their wide range of applications in the medical field. The encapsulation of drugs into the nanoparticles offers several unique characteristics leading to prolonged circulation, improved drug localization, and thus enhanced drug Read More

To cope with environmental issues, scientists strive to develop innovative materials and methods. Bismuth vanadate (BiVO4) has attracted attention because of its significant characteristics like low toxicity, corrosion resistance, photo-stability, narrow band-gap, and ability to provide better efficiency invisible light. However, fast recombination of charge carriers limits its photocatalytic activity. Many researchers have improve Read More

Background: Metronidazole is widely used due to its clinical excellence in treating systemic or local infections caused by anaerobic bacteria. However, it is easily soluble in water, not easy to biodegrade and adsorb and stays for a long time in environments, causing great harm to human health and food safety. Therefore, it is important to choose highly selective and sensitive methods for metronidazole content determinat Read More

Background: Synthesis of spherical silver nanoparticles is mostly reported, but the use of DNA, especially short oligonucleotides, to mediate the production of anisotropic AgNPs is still questioned. Objective: This work aims to use 30-mer oligo(dA) and oligo(dC) (or A30 and C30) to assist the formation of anisotropic AgNPs under blue LED irradiation. Methods: We reported a simple synthesis reaction containing AgNO 3, A30 (o Read More

Background: The study of metallic nanoparticles is important since they present nonlinear optical properties crucial for modern photonic science and technology. Moreover, their mechanical, chemical, and optical properties are different from those presented with respect to volumetric material. Said properties can be adjusted by controlling the size and shape of the studied nanoparticles, and various methodologies hav Read More
