چکیده

We designed and prepared nanoreactors based on a poly(2-methyloxazoline)-block-poly(dimethylsiloxane)-block-poly(2-methyloxazoline (PMOXA-b-PDMS-b-PMOXA) amphiphilic triblock copolymer encapsulating the enzyme penicillin acylase for local and controlled production of antibiotics.

Poly (methacrylic acid-co-acrylic acid)-grafted polyvinylpyrrolidone coated Magnetic nanoparticles as a pH-responsive magnetic Nano-carrier for controlled delivery of antibiotics

Objective(s): Pharmaceutical industries are leading to improved medications that can target diseases more effectively and precisely. Researchers have intended to reformulate drugs so that they may be more safely used in human body. The more targeted a drug is, the lower its chance of triggering drug resistance, a cautionary concern surrounding the use of broad-spectrum antibiotics. The aim of t...

Crumpled graphene nanoreactors.

Nanoreactors are material structures that provide engineered internal cavities that create unique confined nanoscale environments for chemical reactions. Crumpled graphene nanoparticles or "nanosacks" may serve as nanoreactors when filled with reactive or catalytic particles and engineered for a specific chemical function. This article explores the behavior of crumpled graphene nanoreactors con...

Light-responsive polymer nanoreactors: a source of reactive oxygen species on demand.

Various domains present the challenges of responding to stimuli in a specific manner, with the desired sensitivity or functionality, and only when required. Stimuli-responsive systems that are appropriately designed can effectively meet these challenges. Here, we introduce nanoreactors that encapsulate photosensitizer-protein conjugates in polymer vesicles as a source of "on demand" reactive ox...

Development of pH Sensitive Nanoparticles for Intestinal Drug Delivery Using Chemically Modified Guar Gum Co-Polymer

The aim of the research work was to chemically modify guar gum(GG) as a pH sensitive co-polymer and formulating intestinal targeting ESO nanoparticles (NPs) using the synthesized co-polymer. Poly acrylamide-grafted-guar gum (PAAm-g-GG) co-polymer was synthesized by free radical polymerization. Chemical modification of PAAm-g-GG by alkaline hydrolysis results in formation of a pH-sensitive co-po...
