Bacterial infections are a major complication in human healthcare. Bacteria tracing and targeted delivery of antibiotics to bacterial infection sites being developed reduce the high mortality caused by pathogenic infections. Owing challenges accurate diagnosis infection, particularly identification biomaterial‐related bacteria, use bacteria‐targeting nanomaterials has become increasingly import...
One of the greatest challenges in the deployment of chemotherapeutic drugs against brain tumors is ensuring that sufficient drug concentrations reach the tumor, while minimizing drug accumulation at undesired sites. Recently, injection of therapeutic agents following blood-brain barrier (BBB) opening by focused ultrasound (FUS) with microbubbles (MBs) has been shown to enhance drug delivery in ...
This paper devotes a novel micellar structure for cancer theranostics by incorporating magnetic and therapeutic functionalities into a natural sourced targeting polymer vehicle. Heparin-folic acid micelles taking advantage of both excellent loading capability and cancer targeting ability have been employed to simultaneously incorporate superparamagnetic iron oxide nanoparticles (SPIONs) and dox...
Magnetic drug delivery has the potential to target therapy to specific regions in the body, improving efficacy and reducing side effects for treatment of cancer, stroke, infection, and other diseases. Using stationary external magnets, which attract the magnetic drug carriers, this treatment is limited to shallow targets (<5 cm below skin depth using the strongest possible, still safe, practica...
recent advances in nanotechnology have rapidly developed new therapeutic and diagnostic concepts in all aspects of medicine. magnetic nanoparticles (mnps) can be simultaneously functionalized and guided by a magnetic field, thus providing promising tools for several biomedical applications. mnps contrast agents at low concentrations offer the potential to significantly improve existing methods o...
a controlled release matrix formulation for mesalamine was designed and developed to achieve a 24 h release profile. using compritol 888 ato (glyceryl behenate) as an inert matrix-forming agent to control the release of mesalamine, formulation granules containing the solid dispersions were investigated. pectin, a polysaccharide, was used as bacterial dependent polymer for colon targeting. the m...
conclusions our findings revealed that the zfn technology could be employed to overcome ampicillin resistance by the targeted disruption of the ampicillin resistance gene, which leads to inactivation of β-lactam synthesis. therefore, zfn technology could be engaged to decrease the antibiotic resistance issue with the construction of a zfn archive against different args. to tackle the resistance...
We have developed a novel water-dispersible oleic acid (OA)-Pluronic-coated iron oxide magnetic nanoparticle formulation that can be loaded easily with high doses of water-insoluble anticancer agents. Drug partitions into the OA shell surrounding iron oxide nanoparticles, and the Pluronic that anchors at the OA-water interface confers aqueous dispersity to the formulation. Neither the formulati...
Optimization methods are presented to design Halbach arrays to maximize the forces applied on magnetic nanoparticles at deep tissue locations. In magnetic drug targeting, where magnets are used to focus therapeutic nanoparticles to disease locations, the sharp fall off of magnetic fields and forces with distances from magnets has limited the depth of targeting. Creating stronger forces at depth...
