Stimuli responsive drug delivery

Hydrogels are the upcoming class of biomaterials, which act as excellent drug delivery systems. These materials have important characteristic feature that they respond to various external stimuli like pH, light, temperature, magnetic field, electric field and pressure. molecular polymers and supramolecular pseudorotaxanes for stimuli-responsive drug delivery, which not only endow the delivery systems with ﬂexible and robust attributes of non-covalent interactions but also meet the urgent need of human healthcare.18–20 Drug-delivery systems immobilized with supramolecular nanovalves, emerging as a Uncontrolled cell proliferation, peculiar nutritional environment and metabolic patterns change of tumor tissues generated acidic pH, elevated temperature, overexpressed proteins/enzymes, high levels of oxidation-deoxidation environment (GSH/ROS), which could be regarded as endogenous triggers. 11,12 Exogenous stimuli are also used in single stimulus-responsive drug-delivery system (SSR-DDSs Stimuli‑responsive drug delivery systems based on mesoporous silica nanoparticles Wong, Eddy Mun Fei 2018 Wong, E. M. F. (2018). Stimuli‑responsive drug Smart External Stimulus-Responsive Nanocarriers for Drug and Gene Delivery Authors Mahdi Karimi, Parham Sahandi Zangabad, Amir Ghasemi and Michael R Hamblin Published Programmed drug delivery was achieved by a dual response of the extracellular acid and intracellular reductive environment.

The “stimuli-responsive molecularly imprinted polymers” reviewed in this paper are expected to contribute significantly to the exploration and development of new generations of intelligent and self-regulated drug delivery systems. Keywords: Molecularly imprinted polymers, stimuli-responsive systems, intelligent drug delivery Stimuli-Responsive Materials for Controlled Drug Delivery Stimuli-responsive materials, which exhibit changes in one or more properties in response to an external trigger, have gained interest due to their tunability and versatility.

Stimuli-responsive polyelectrolyte brushes switch as a function of pH such as bioanalytics, protein purification, and protein drug-delivery.

A greater amount of MRSA in the system will lead to more release of drug and vice versa. Carbon-dot-coated novel alginate beads (CA-CD) exhibiting superior stability was successfully used as smart drug delivery vehicle.

Multifunctional mesoporous silica nanospheres for biosensor, stimuli-responsive controlled-release drug delivery carriers and gene transfection vectors;The

(Click on the image to enlarge.) Stimuli-responsive liposomes for drug delivery The ultimate goal of drug delivery is to increase the bioavailability and reduce the toxic side effects of the active pharmaceutical ingredient (API) by releasing them at a specific site of action. Biological stimuli responsive drug carriers based on keratin for triggerable drug delivery 2013-10-23 · Spurred by recent progress in materials chemistry and drug delivery, stimuli-responsive devices that deliver a drug in spatial-, temporal- and dosage-controlled fashions have become possible. Interest in stimuli-responsive polymers is steadily gaining increasing momentum especially in the ﬁelds of controlled and self-regulated drug delivery. Delivery systems based on these polymers are developed to closely resemble the normal physiological process of the diseased state ensuring optimum drug release according to the physiological need. Various advantages of hydrogels as drug delivery system come from their good transport properties, ability to protect drugs, proteins and peptides from the environment, bio- degradability and can be modified according to the route Drug Deliv, 2015; 22(2): 145–155!

Poly (N-isopoprylacrilamide). Poloxamers. The ideal drug delivery system is the one in which the drug delivery profile is able to respond to metabolic states and/or physiological variations (Bawa et al., 2009). This kind of The increased understanding of molecular aspects associated with chronic diseases, such as cancer and the role of tumor microenvironment, has led to the identification of endogenous and exogenous stimuli that can be exploited to devise “stimuli-responsive” materials for site-specific drug delivery … 2021-01-01 Stimuli-responsive drug-delivery nanocarriers (DDNs) have been increasingly reported in the literature as an alternative for breast cancer therapy. Stimuli-responsive DDNs are … However, the MOF families and members, and the drug release mechanisms in MOF-based stimuli-responsive drug delivery systems (DDSs) are rarely summarized. Here, we systematically classified the families of MOF and introduced some representative members in MOF families.

2017). In a joint collaboration with Dr. Bucio at UNAM, we have applied g-ray irradiation for the grafting of stimuli-responsive networks that regulate drug diffusion as a function of the surrounding conditions 22,23, resulting in medical devices with the capability of acting as DDS. 7 The functionalization may also improve hemocompatibility, change the protein pattern adsorption and inhibit biofilm Stimuli-responsive nanocarriers for drug delivery, tumor imaging, therapy and theranostics Peng Mi Department of Radiology, Center for Medical Imaging, and State Key Laboratory of Biotherapy and Cancer Center, West China Hospital, Sichuan University, No.17 South Renmin Road, Chengdu, 610041, China Traditional drug-delivery systems suffer some drawbacks, especially premature drug release and the lack of diverse stimuli responsiveness. The partnership between suitable solid support-based drug nanocarriers and supramolecular nanovalves led to a variety of gated materials containing supramolecular switches and polymers that are capable of targeted delivery and on-demand release of drugs Purchase Stimuli Responsive Polymeric Nanocarriers for Drug Delivery Applications - 1st Edition. Print Book & E-Book. ISBN 9780081019955, 9780081019962 delivery systems activated by external remote triggers are also discussed.
