This review presents the most outstanding contributions in the field of biodegradable polymeric nanoparticles used as drug delivery systems. Methods of preparation, drug loading and drug release are covered. The most important findings on surface modification methods as well as surface characterization are covered from 1990 through mid-2000.
Considerable research efforts have been directed towards developing safe and efficient chitosan-based particulate drug delivery systems. The present review outlines the major new findings on the pharmaceutical applications of chitosan-based micro/nanoparticulate drug delivery systems published over the past decade. Methods of their preparation, drug(More)
Biodegradable nano/microparticles of poly(D,L-lactide-co-glycolide) (PLGA) and PLGA-based polymers are widely explored as carriers for controlled delivery of macromolecular therapeutics such as proteins, peptides, vaccines, genes, antigens, growth factors, etc. These devices are mainly produced by emulsion or double-emulsion technique followed by solvent(More)
Glutaraldehyde crosslinked interpenetrating polymer network (IPN) blend microspheres of chitosan (CS) and hydroxyethyl cellulose (HEC) were prepared in the form of microspheres (66-82 microm dia) and investigated for the controlled release (CR) of isoniazid (INH), an antituberculosis drug. Microspheres were characterized by X-ray diffraction (XRD) to study(More)
INTRODUCTION The ever-increasing developments in pharmaceutical formulations have led to the widespread use of biodegradable polymers in various forms and configurations. In particular, interpenetrating network (IPN) and semi-IPN polymer structures that are capable of releasing drugs in a controlled manner have gained much wider importance in recent years.(More)
Novel semi-interpenetrating polymer network (IPN) hydrogel microspheres of chitosan (CS) and hydroxypropyl cellulose (HPC) were prepared by emulsion-cross-linking method using glutaraldehyde (GA) as a cross-linker. Chlorothiazide (CT), a diuretic and anti-hypertensive drug with limited water solubility, was successfully encapsulated into IPN microspheres.(More)
This paper reports the development of new interpenetrating polymeric networks of sodium alginate with gelatin or egg albumin cross-linked with a common cross-linking agent, glutaraldehyde, for the in-vitro release of cefadroxil. The beads formed were characterized by Fourier transform infra-red spectroscopy, scanning electron microscopy and differential(More)
A simple and commercially viable method of preparation of chitosan microparticles (MPs) was adopted for the entrapment of clozapine, which can be easily scaled-up to controlled drug delivery dosage form. This method is devoid of tedious processes like emulsification in oil phase, spray-drying, etc. MPs have been prepared by changing the experimental(More)
UNLABELLED "Tech mining" applies bibliometric and text analytic methods to scientific literature of a target field. In this study, we compare the evolution of nano-enabled drug delivery (NEDD) systems for two different applications - viz., brain cancer (BC) and Alzheimer's disease (AD) - using this approach. In this process, we derive research intelligence(More)
This paper presents experimental results on the successful encapsulation of a natural liquid pesticide 'neem (Azadirachta Indica A. Juss.) seed oil' hereafter designated as NSO, using sodium alginate (Na-Alg) as a controlled release (CR) polymer after crosslinking with glutaraldehyde (GA). The NSO-containing beads have been prepared by changing the(More)
