A Molecular Modeling Approach towards Engineering of Polymer Nanogels for Controlled Drug Delivery

Dutta R.C., Rai B., Tata Research Development and Design Centre, IN

Traditionally, a drug is administered initially at a higher dosage so as to repeat the next dose after several hours or days. This, besides being un-economical, results in side effects. Recently, there has been an [...]

The utilization smart hydrogels and composites with controllable porosity in the preparation of metal nanocatalyst

Sahiner N., Ozay O., Sagbas S., Yasar A., Aktas N., Canakkale Onsekiz Mart University, TR

There is great need for versatile and smart support materials. As many industrial and biologic reactions take place in water (green chemistry), systems that operates in water and mechanically durable, flexible with controllable porosity, and [...]

Mammalian cells in nanocapsules:fiber production in co-flowing ambient liquid stream

Sharma A., Sharma R., Sharma A., Sharma R., Innovations and Solutions Inc., US

Mammalian cell-enclosed in nanocapsules have been investigated as devices for bioproduction, cell therapy and stem cell research. Reduction in the diameter of the vehicles is an important issue as it induces beneficial effects such as [...]

Responsive Hydrogels as Model Materials to Study the Deformation Behavior of Patterned Polymer Nanostructures

Tirumala V.R., Stafford C.M., Huang R., Lin E.K., Ocola L.E., National Institute of Standards and Technology, US

The mechanical stability of polymer nanolines is crucial to the success of semiconductor device fabrication. Recent experimental and modeling studies have focused on the influence of processing conditions on the stability of densely patterned lines. [...]

Electrically Triggered Hydrogels: Mathematical Models and Simulations

Chatterjee A.N., De S.K., Aluru N.R., University of Illinois, US

Environmentally sensitive hydrogels have enormous potential in various applications. Ionic polymer gels have been shown to respond to a number of different stimuli like pH and electric field. One of the major advantages of electro-responsive [...]

Modeling of Ionic Hydrogel Kinetics in Buffered Solutions

Ohs R.R., De S.K., Aluru N.R., University of Illinois at Urbana-Champaign, US

In this paper, we present the meshless Finite Cloud Method (FCM) for the solution of a time-dependent partial differential equation governing ionic gel swelling. Using a point distribution, FCM constructs interpolation functions without assuming any [...]
