Single-walled carbon nanotubes (SWNT) in a poly(ethylene)ghycol solution are a biocompatible transporters with strong optical absorption in the near-infrared region, in which the biological tissue is almost transparent with very low absorbance. Here, antibody-functionalized SWNTs for tumor early detection with photoacoustic molecular imaging in vivo are reported. To lay the groundwork for this ...

Alginate is being explored widely for an array of medicinal and diagnostic measures by way nanosystems fabricated techniques along the lines drug delivery, imaging, tissue regeneration, etc. Their biocompatibility, nontoxicity, sensitivity to pH, mucoadhesiveness, biodegradability have invited extensive body work in this field. gelling ability facilitates encapsulation different molecules like ...

In this work, a novel protocol was developed for size tuning and cetyltrimethylammonium bromide (CTAB) removal of gold nanorods using commercially available nonionic fluorosurfactants (FSN), an excellent candidate for PEG and other modification reagents. The tunable gold nanorods can easily be obtained by stopping the ligand replacement reaction at different time intervals. The FSN-coated gold ...

Nanocellulose is a relatively inexpensive, highly versatile bio-based renewable material with advantageous properties, including biodegradability and nontoxicity. Numerous potential applications of nanocellulose, such as its use for the preparation of high-performance composites, have attracted much attention from industry. Owing to the low energy consumption and the addition of significant val...

Growing interest in Fe2O3 as a light harvesting layer in solar energy conversion devices stems from its unique combination of stability, nontoxicity, and exceptionally low material cost. Unfortunately, the known methods for conformally coating high aspect ratio structures with Fe2O3 leave a glaring gap in the technologically relevant temperature range of 170-350 C. Here, we elucidate a self-lim...

A visible light responsive photocatalytic hybrid with excellent photoelectrochemical activity was first fabricated via the self-assembly of Au nanorods onto poly(l-cysteine) modified graphitic carbon nitride nanosheets. Herein, layered structural graphitic carbon nitride nanosheets with a proper band gap, high stability, and nontoxicity, as a photoactive material, demonstrate a high photocataly...

We examine adaptive allocation designs for the problem of determining the optimal therapeutic dose for subjects in early-phase clinical trials. A subject can fail due to lack of efficacy or due to a toxic reaction. Successful subjects will have both a positive response and no toxic side effects. Thus, we seek to maximize the product of the nontoxicity and efficacy dose-response curves. We are i...

The composition of the dressings is based on polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), and agar. The electron beam irradiation technique has been used to prepare hydrogel wound dressings. The in vitro biocompatibility of the hydrogel was investigated by check samples (hydrocolloid Comfeel), antibacterial test (Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginos...

The literature concerning the oxidative oligomerization and polymerization of various arylamines, e.g., aniline, substituted anilines, aminonaphthalene and its derivatives, catalyzed by oxidoreductases, such as laccases and peroxidases, in aqueous, organic, and mixed aqueous organic monophasic or biphasic media, is reviewed. An overview of template-free as well as template-assisted enzymatic sy...

CsSnI3 is a potential lead-free inorganic perovskite for solar energy applications due to its nontoxicity and attractive optoelectronic properties. Despite these advantages, photovoltaic cells using CsSnI3 have not been successful to date, in part due to low stability. We demonstrate how gradual substitution of Rb for Cs influences the structural, thermodynamic, and electronic properties on the...
