                                                                               JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract This review is devoted to recent progress in the design of anticancer drug delivery systems with participation of unique polysaccharide gellan gum. At first a brief literature survey on conformational and phase behavior of gellan gum as a function of external stimuli, such as temperature, pH, salt addition etc. is presented. Then the immobilization protocol of anticancer drugs and gold nanoparticles within gellan-based hydrogel matrix is discussed. Release of anticancer drugs from gellan gel matrix to outer solution is considered. Cytotoxicity of gellan gum-immobilized gold nanoparticles together with their anticancer activity is summarized. Keywords: Gellan gum; Coil-helix transition; Hydrogel; Anticancer drugs; Gold nanoparticles; Cytotoxicity; Anticancer activity Abbrevations: GG: Gellan Gum; EOR: Enhanced Oil Re

                                                                                    JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Commercially available plastics are commonly used in day to day life. The rate of accumulation of plastic in the environment is increasing day by day which becomes a major universal concern due to its less biodegradation property. Generated plastic waste is managed by incineration or landfill disposal. These processes are time -consuming and expensive. The main objective of the study involves the investigation bio-degradable polymers viz Polyhydroxybutyrate (PHB) produced by bacterial species (Alcaligenes). The stock culture of Alcaligenes species was cultured at a rate of 5% in production media containing 2.5% of sucrose. The growth was quantified through optical density, biomass and PHB. The biomass of the culture was 2.7g/l. The growth curve was obtained that was following the same trend. The PHB was estimated through gas chrom

                                                                                           JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Deep Eutectic Solvents (DESs), a subclass of ionic liquids, have emerged as sustainable and green solvents in chemical reactions. In this mini-review article, deep eutectic solvents utilization in the polymer synthesis will be discussed briefly. Keywords: Deep eutectic solvents; Polymer synthesis; Green chemistry Abbrevations: DES: Deep Eutectic Solvents; HBA: Hydrogen Bond Acceptor; HBD: Hydrogen Bond Donor; PDCs: Poly Diol-Co-Citrates; PAAc: Poly (Acrylic Acid); PMAAc: Poly Methacrylic Acid; APS: Ammonium Persulfate; EM: Eutectic Mixture; FP: Frontal polymerization  Introduction Solvent utilization creates the largest volume of auxiliary waste in polymer synthesis. However, increasing awareness of the environmental problems has led to the use of alternative reaction media to reduce or elimina
