Development of In-Vivo Screening Benchmarks for Complex Engineered Nanomaterials

Mahoney S., Najera M., Bai Q., Burton E., Veser G., University of Pittsburgh, US

This works investigates embedding metal nanoparticles (NPs) in porous silica shells to reduce or entirely mitigate the metal NPs toxicity while still providing access to the metal NP surface; hence maintaining functionality of the embedded [...]

Cytotoxicity and biointeractions of nanosilver in macrophages

Pratsinis A., Pratsinis S.E., Hervella P., Leroux J.-C., Pratsinis A., Pratsinis S.E., Sotiriou G.A., ETH Zürich, CH

Silver nanoparticles (nanosilver) are broadly used today in textiles, food packaging, household devices and bioapplications, prompting a better understanding of their toxicity and biological interactions. Here, nanosilver of well-defined size (5.7 to 20.4 nm) supported [...]

Effects of Solvents on Dissolution of Photoresist in Parylene Microchannels

Ceylan Koydemir H., Kulah H., Ozgen C., Tosun I., Middle East Technical University, TR

This paper presents a detailed study for the effects of different types of solvents on dissolution of photoresist inside the parylene micro-channels, for the first time. Experimental results indicate that photoresist dissolution in dipolar aprotic [...]

Process Development and Industrial Manufacturing of Nanotechnology-Based Pharmaceuticals

Hassan E., Gumudavelli S., Pharmaceutics International Inc. (Pii), US

Process design and development of oral, topical and parentral nanotechnology-based pharmaceuticals are presented. Factors affecting process output and scale-up choices for various dosage forms are discussed with emphasis on critical parameter control and optimization. For [...]

Dissolution of Hydrogen Bonded Polymers in Water: From Synthetic to Biopolymers

Rastogi S., Vinken E., Harings J., Yin J., Terry A., Eindhoven University of Technology, NL

The field of supramolecular materials explores the use of intermolecular, non-covalent bonding to obtain novel self-assembled structures. Self-assembly is a method of spontaneous organisation of molecules into higher order structures ranging from the nano to [...]

A Semi-Empirical Resist Dissolution Model for Sub-micron Lithographies

Khan M., Bollepalli S.B., Cerrina F., UW-Madison, US

In this paper, we present a new resist dissolution model suitable for large range of application domains - from memory devices employing < 130nm design rules to MEMS devices with design rules exceeding 10s of [...]
