Galactomannan armed superparamagnetic iron oxide nanoparticles as a folate receptor targeted multi-functional theranostic agent in the management of cancer.

Superparamagnetic iron oxide nanoparticles (SPIONs) represent a versatile class of theranostics with profound applications in biomedicine. An eco-friendly modification of SPIONs was attempted with a 110 kDa galactomannan (PSP001) isolated from the fruit rind of Punica granatum. The PSP001 appended SPIONs favor unique advantages including tumor-targeted accumulation and improved biocompatibility.

Folic acid-appended galactoxyloglucan-capped iron oxide nanoparticles as a biocompatible nanotheranostic agent for tumor-targeted delivery of doxorubicin.

Iron oxide nanoparticles (IONPs) are employed as MRI contrast agents and as effective drug delivery vehicles. However, the limited solubility and biodegradability of these nanoparticles need to be improved for safer biomedical applications. In an attempt to improve the bottlenecks associated with IONPs, the current study focuses on the synthesis of folic acid conjugated, galactoxyloglucan-iron oxide nanoparticles (FAPIONPs), for the loading and controlled release of the encapsulated chemotherapeutic agent doxorubicin (DOX).

A biocompatible glycol-capped nano-delivery system with stimuli-responsive drug release kinetics abrogates cancer cell survival.

An eco-friendly polysaccharide (PSP001) isolated from the fruit rind of Punica granatum is a biodegradable polymer with immunostimulatory and anticancer properties. PSP001 was employed for the stimuli-responsive targeted delivery of antineoplastic agent doxorubicin (Dox) by the fabrication of Dox-holding PSP nanoparticles (DPN). The galactose moieties of PSP001 were occupied as an effective tumor-targeted motif against the over-expressed asialoglycoprotein and galectin receptors of cancers.

Doxorubicin eluting microporous polysaccharide scaffolds: An implantable device to expunge tumour.

A variety of naturally derived and synthetic biomaterial scaffolds have been investigated as 3D environments for supporting cell growth and can be used to achieve drug delivery with high loading efficiency. Polysaccharides which enhance the tumour-specific drug release are ideal candidates for scaffold preparation in combination with chemotherapeutic agents for the management of solid tumours by local applications. Galactoxyloglucan (PST001) based porous scaffolds (PS) were prepared by crosslinking and freeze drying with a porosity of 90%.

Semi-interpenetrating nanosilver doped polysaccharide hydrogel scaffolds for cutaneous wound healing.

The extensive advancement with novel wound dressing materials functionalized with desirable properties, often touted as a panacea for cuts and burns afflicting various pathologies. However, it would indeed be a hard task to isolate any such material which perfectly fits the needs of any biomedical issue at hand. Biocompatibility, biodegradability as well as non-toxicity of natural polysaccharide served as a versatile and tunable platform for designing natural polysaccharide based scaffolds as an attractive tool in tissue engineering with a greater degree of acceptability.
