Recent Patents on Nanotechnology - Volume 14, Issue 3, 2020

Background: Current cerebral drug delivery to the brain and Cerebrospinal Fluid (CSF) is limited by the Blood-Brain Barrier (BBB) or the blood-blood Cerebrospinal Fluid (CSF) barrier. The popular, non-invasive, intranasal delivery provides an exciting route for topical and systemic applications. For example, intranasal drug delivery of Central Nervous System (CNS) drugs can be designed to pass the BBB barrier via the nose-to-brain Read More

Background: Hypertension comes under the category of chronic disease, which requires long term treatment. Hypertension is usually treated by oral administration of various therapeutic agents. There are several limitations of the oral route, making pharmaceutical scientists to discover an alternative route for drug delivery. Methods: The transdermal route may be a better alternative as it shows various advantages like lack Read More

Background: The purpose of this study was to formulate, characterize and in-vitro cytotoxicity of 5-Fluorouracil loaded controlled release nanoparticles for the treatment of skin cancer. The patents on nanoparticles (US8414926B1), (US61654404A), (WO2007150075A3) etc. helped in the selection polymers and method for the preparation of nanoparticles. Methods: In the present study nanoparticles were prepared by Read More

Aims: The purpose of this work was to obtain a hydrophobic sorbent material with potential applications in oil spill remediation. Background: The accidents due to oil spills cause long-term ecological damage, especially in the aquatic environment. The cleaning of oil spills can be carried out by many methods and techniques, being absorbents the most attractive due to the possibility of recovery and complete elimination of the Read More

Background: The ability to form biofilm and produce several virulence factors has caused numerous human pathogens to become tremendously resistant towards traditional antibiotic treatments, thus, new alternative strategies are urgently in demand. One of the strategies that have recently been developed involves the application of metallic Nanoparticles (NPs). Up to the present, promising results in terms of antimicrobial a Read More

Aims: To use an agroindustrial waste (orange peels) as a source of polyphenols as a reducing medium for obtaining silver nanoparticles by greener method. Background: Several techniques have been employed for AgNPs synthesis, nevertheless, most of them involve the use of toxic chemicals in the process. The use of fungi, bacteria, and plant extracts as subtracts for green synthesis is an ecofriendly alternative, although hypo Read More
