Action at a Distance: Functional Drug Delivery Using Electromagnetic-Field-Responsive Polypyrrole Nanowires
In this work, we introduce a free-standing, vertically aligned conductive polypyrrole (Ppy) architecture that can serve as a high-capacity drug reservoir. This novel geometric organization of Ppy provides a new platform for improving the drug-loading efficiency. Most importantly, we present the first formal evidence that an impregnated drug (dexamethasone, DEX) can be released on demand by a fo...
متن کامل‘Spooky action at a distance’ in the Micropolar Electromagnetic Theory
Still now there are no theoretical background for explanation of physical phenomena of ‘spooky action at a distance’ as a quantum superposition of quantum particles. Several experiments shows that speed of this phenomena is at least four orders of magnitude of light speed in vacuum. The classical electromagnetic field theory is based on similarity to the classic dynamic of solid continuum media...
متن کاملBiosensing and drug delivery by polypyrrole.
Conducting polypyrrole is a biological compatible polymer matrix wherein number of drugs and enzymes can be incorporated by way of doping. The polypyrrole, which is obtained as freestanding film by electrochemical polymerization, has gained tremendous recognition as sophisticated electronic measuring device in the field of sensors and drug delivery. In drug delivery the reversing of the potenti...
متن کاملActuation of polypyrrole nanowires.
Nanoscale actuators are essential components of the NEMS (nanoelectromechanical systems) and nanorobots of the future, and are expected to become a major area of development within nanotechnology. This paper demonstrates for the first time that individual polypyrrole (PPy) nanowires with diameters under 100 nm exhibit actuation behavior, and therefore can potentially be used for constructing na...
متن کاملROS‐responsive drug delivery systems
Reactive oxygen species (ROS) play an important role in signal transduction and metabolism. Over-produced ROS in cells or tissues, however, often leads to oxidation stress that has implications in a series of diseases including cancer, aging, atherosclerosis and inflammation. Driven by the need for on-demand drug delivery and fuelled by recent development of ROS-responsive materials and nanomed...
