Living systems react to external stimuli by responding and adapting to changing external 2.3 Artificial Smart polymers, stimuli-responsive polymers or functional polymers are high-performance polymers that change according to the environment they are in. Such materials can be sensitive to a number of factors, such as temperature, humidity, pH, chemical compounds, the wavelength or intensity of light or an electrical or magnetic field and can respond in various ways, like altering colour or 2004-12-01 · Stimuli-responsive polymers are defined as polymers that undergo relatively large and abrupt, physical or chemical changes in response to small external changes in the environmental conditions. Names coined for ‘stimuli-responsive’ polymers have been given as stimuli-sensitive [4] , intelligent [5] , smart [6] , [7] , or environmentally sensitive polymers [8] . Polymers that can respond to external stimuli are of great interest in medicine, especially as controlled drug release vehicles. In this critical review, we consider the types of stimulus response used in therapeutic applications and the main classes of responsive materials developed to date. Pris: 449 kr.
Stimuli-responsive polymers for oral insulin delivery 23. Stimuli-responsive Polysaccharides for Colon Targeted Drug Delivery. Part VII - Future Trends and 2012-02-11 · The strategy underlying polymer-containing responsive systems is a dramatic physicochemical change caused by stimuli. At the macromolecular level, polymer chains can be altered in different ways, including changes in hydrophilic-to-hydrophobic balance, conformation, solubility, degradation, and bond cleavage, and these, in turn, will cause detectable behavioral changes to self-assembled Thermosensitive polymers Thermosensitive polymers are the most widely studied stimuli–responsive polymers, since temperature can easily be used to trigger and control drug release at tumor sites (Gil & Hudson, 2004). The idea of using temperature as a stimulus arose partly from the fact that tumor microenviron- Stimuli-responsive polymers and nanomaterials for gene delivery and imaging applications. Shim MS(1), Kwon YJ. Author information: (1)Department of Chemical Engineering and Materials Science, University of California, Irvine, 92697, USA. The researchers provide an overview in their paper of how some of the latest stimuli-responsive biomaterials (SRBs), which include the shape memory polymer, are used to mimic the dynamic This book provides a general introduction to nanogels and the design of various stimuli-sensitive nanogels that can control drug release in response to specific stimuli.

Polymeric materials designed to change properties in response to a stimulus. Stimuli-responsive gels (hydrogels, when the swelling agent is an aqueous solution) are a special kind of swellable polymer networks with volume phase transition behaviour. These materials change reversibly their volume, optical, mechanical and other properties by very small alterations of certain physical (e.g.

As a result, these stimuli-responsive devices 2013-04-19 Stimuli-responsive polymers or so-called “smart polymers” are macromolecules that are sensitive to certain triggers from the external environment, including … Stimuli-responsive polymers or macromolecules also exhibit the ability to convert biochemical and chemical signals into mechanical, thermal, optical, and electrical signals, and vice versa, for which they are utilized in an array of applications like “smart” optical systems, drug delivery, diagnostics, and tissue engineering, in conjunction with coatings, textiles, biosensors, and microelectromechanical systems. The stimulus used for fixing and releasing the temporary shape will thus depend on the choice of the latter. Most shape memory polymers studied so far respond to a change in temperature, but many alternative switching schemes have been developed where the shape memory effect is driven by exposure to light, chemicals, or other stimuli. high performance stimuli-responsive polymeric materials.
