Targeted delivery of cells and therapeutic agents would benefit a wide range of biomedical applications by concentrating the therapeutic effect at the target site while minimizing deleterious effects to off-target sites. Magnetic cell targeting is an efficient, safe, and straightforward delivery technique. Superparamagnetic iron oxide nanoparticles (SPION) are biodegradable, biocompatible, and ...
Poly(D,L-lactic-co-glycolic acid) (PLGA) is an important material used in drug delivery when controlled release is required. The purpose of this research is to design and characterize PLGA microparticles (PLGA MPs) implants for the controlled release of nicardipine hydrochloride (NCH) in vitro. This study used the water-in-oil-in-water (w1/o/w2) double emulsion and solvent diffusion/evaporation...
In this study, fluconazole (FLZ) loaded poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) were prepared with two different formulations consisting of polyvinyl alcohol (PVA) and PVA-rhamnolipid (R) in order to improve antibiofilm activity against Candida albicans ATCC 90028. The encapsulation efficiency, drug loading capacity, in-vitro release, characterization these compared. Character...
Poly(D,L-lactide-co-glycolide) (PLGA) is the most frequently used biodegradable polymer for developing nano/ microparticles encapsulating therapeutic drugs in controlled release (CR) applications. PLGA based drug delivery devices have several advantages over the conventional devices. One of the advantage is the extended release rates of drugs up to days, weeks or months. Other reasons for the w...
the main objective of the present study was to formulate gastroretentive effervescent sustained release drug delivery systems of risperidone floating tablets with the help of methocel® k15, ethocel® standard 7fp premium, eudragit ® rs100 sustained release polymers to improve its safety profile, bioavailability and patient compliance. risperidone floating tablets were formulated by wet granulati...
The power of tumorigenesis, chemo-resistance and metastasis in malignant ovarian tumors resides in a tiny population of cancer cells known as ovarian cancer stem cells (OCSCs). Developing nano-therapeutic targeting of OCSCs is considered a great challenge. The potential use of poly(lactic-co-glycolic acid) nanoparticles (PLGA NPs) was investigated as a drug delivery system for paclitaxel (PTX) ...
Drug Delivery In article number 2000069, Boaz Mizrahi and co-workers report a new nano delivery system that is based on injectable liquid copolymer. The copolymer, starPEG-PLGA (red blue in the image) mixed with drug (green spheres without any solvents or excipients. After mixture injected into body, copolymer self-assembles situ well-defined nanoparticles.
A amphiphilic block copolymer composed of conventional monomethoxy (polyethylene glycol)-poly (d,l-lactide-co-glycolide)-poly (l-lysine) (mPEG-PLGA-b-PLL) was synthesized. The chemical structure of this copolymer and its precursors was confirmed by Fourier Transform Infrared Spectroscopy (FTIR), (1)H Nuclear Magnetic Resonance ((1)H NMR) and Gel Permeation Chromatography (GPC). The copolymer wa...
BACKGROUND Aerosolized therapeutics hold great potential for effective treatment of various diseases including lung cancer. In this context, there is an urgent need to develop novel nanocarriers suitable for drug delivery by nebulization. To address this need, we synthesized and characterized a biocompatible drug delivery vehicle following surface coating of Fe3O4 magnetic nanoparticles (MNPs) ...
Recently, photothermal therapy has become a promising strategy in tumor treatment. However, the therapeutic effect was seriously hampered by the low tissue penetration of laser. Therefore, in this study, radiofrequency (RF) with better tissue penetration was used for tumor hyperthermia. First, one type of gold nanorods (AuNRs) suitable for RF hyperthermia was selected. Then, poly(lactic-co-glyc...
