Design, synthesis and characterization of fluorescent hyperbranched polyglycerols and organic nanoparticles with covalently bound anti-fading agents
… Through the iterative use of ROMP and RCM, organic nanoparticles (ONPs) were synthesized incorporating multiple fluorescein and AFA units. The ONPs were brighter and more photostable than fluorescein. The photostability of the ONPs without AFAs was found to loosely correlate to its …

Semiconducting Polymer Nanospheres: Organic Alternatives to Inorganic Quantum Dots?
Semiconducting polymer nanospheres are organic conjugated polymer nanoparticles which are synthesized from benign materials and exhibit excellent fluorescence properties. The nanoparticles are generally larger than inorganic quantum dots with a relatively broad size distribution. Quantum dots, on …

Nano-pipette as nanoparticle analyzer and capillary gated ion transistor
<p>The ability to precisely count inorganic and organic nanoparticles and to measure their size distribution plays a major role in various applications such as drug delivery, nanoparticles counting, and many others. In this work I present a simple resistive pulse method that allows translocations, …

Development of Photochemical Surface Modification Technique
… Three, we address the challenge of applying nanoparticles to surfaces. We introduce a fairly well known photochemical surface modification technique to fabricate nanoparticle-films. By using a phthalimide self-assembled monolayer on a glass substrate, we photo-grafted organic nanoparticles to …

Synthesis and Characterization of Protein-Polymer Core-Shell Structures
<p>Proteins and bionanoparticles (BNPs) are the key building blocks of all biological matters. The study of their self-assembly behavior with various polymers is of increasing interest for development of functional materials. Compared to inorganic or organic nanoparticles, BNPs are truly …

Synthesis of Fluorene-based derivatives, Characterization of Optical properties and their Applications in Two-photon Fluorescence Imaging and Photocatalysis
… Two of the common NLO applications in which organic materials have been used are three-dimensional (3D) fluorescence imaging and optical power limiting. Two-photon absorbing materials are, therefore, in great demand to meet the needs of emerging technologies. Organic molecules show great …
