Res., 27, 73 2018 Synthesized silver nanoparticles AgNP were stabilized by encapsulating into the scaffold of bovine serum albumin BSA functionally modified with photosensitive dye 2-[ E 3-hydroxynaphthalen-2-yl diazenyl] benzoic acid. The optical properties, structural properties, and morphology of the developed system were studied. The antibacterial properties and light induced antibacterial reactivity of the AgNP-BSA-dye system were established. The AgNP encapsulated functionally modified system acquired excellent antibacterial activity that was increased by light irradiation. CO2/N2 Separation U...

고분자 과학과 기술 제 30 권 1 호 2019년 2월 117 「Macromolecular Research」목차 정기간행영문지_ 27권 2호 ․ 2019년 2월 The interpenetrating polymer network IPN hydrogels were successfully developed via horseradish peroxidase-mediated dual cross-linking reactions. The IPN hydrogels exhibited independently controllable physicochemical properties, resistance to the proteolytic enzymes, and cytocompatibility for a long-term culture of cancer cells. Also, we utilized the engineered tumor construct as a platform to evaluate the effect of matrix stiffness on cancer cell proliferation and drug resistance. In conclusion, we suggest that our IPN hydrogel is a promising material to study cancer biology and to screen innovative therapeutic agents for better clinical outcome.

｢Macromolecular Research｣ 목차 고분자 과학과 기술 제 30 권 1 호 2019년 2월 119 Synthesis, Characterization and in vitro Drug Release Studies of Sonolytically Intercalated Poly o-anisidine Montmorillonite Nanocomposites Anurakshee Verma and Ufana Riaz* Macromol. Res., 27, 140 2019 Intercalation and polymerization of poly o-anisidine in the interlayer space of montmorillonite MMT takes place via ultrasonic cavitation. When clay particles dispersed in water and exposed to ultrasonic vibrations, alternating expansive as well as compressive acoustic waves create acoustic cavities/bubbles that penetrate into the interlayer space of MMT. This leads to expansion of gallery height. The acoustic bubbles accumulate high ultrasonic energy and subsequently collapse after attaining a critical size, thereby releasing the energy stored in the bubble which is utilized by the monomer and the initiator present in the reaction mixture to undergo polymerization. This causes insertion of ...

Res., 27, 198 2019 In this study, microcapsules with polyurea shells were prepared from oil-in-water O/W emulsion under various agitation speeds 230, 500, and 700 rpm to encapsulate cumene hydroperoxide CHP and tert-butyl peroxy-2-ethly hexanoate TBPEH Thus prepared microcapsule size and shell contents were observed to be decreased upon increasing the agitation speed. Differential scanning calorimetry DSC was used to measure and compare the effect on the reaction kinetics of the methyl methacrylate MMA radical polymerization in the presence of various initiators. When encapsulated initiator used instead of unencapsulated initiator the maximum conversion and maximum reaction rate...
