Feeding Cells with a Novel “Trojan” Carrier: Citrate Nanoparticles
In this work, the preparation of novel calcium citrate (CaCit) nanoparticles (NPs) has been disclosed and the use of these NPs as “Trojan” carriers has been demonstrated. The concentration ratio between calcium ions and citrate ions was optimized, yielding spherical NPs with size in the range of 100–200 nm. Additionally, a fluorescent dye, fluorescein isothiocyanate …

Synthesis, characterization, and hole-transporting properties of benzotriazatruxene derivatives
Hole-transport is an important process in electronic devices such as organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs). However, the molecular structures required for hole-transporting materials in OFET and OLED applications are quite different. In this paper, we examined the effect of alkylation onto a disk-like shaped molecule both in OFET and OLED devices. …
Thread-based platform for nitrite detection based on a modified Griess assay
A new thread-based platform was developed for colorimetric detection of nitrite based on a modified Griess assay. Cellulose thread was functionalized with a p-aminobenzoyl group and impregnated with chromotropic acid as a coupling reagent. The reactions including diazotization and coupling reaction occurred along the length of the thread and a pink colored band was produced …

Facile and green synthesis of pullulan derivative-stabilized Au nanoparticles as drug carriers for enhancing anticancer activity
In this work, we report for the first time AuNPs reduced/stabilized/capped with modified para-aminobenzoic acid-quat188-pullulan (PABA-QP) as excellent nanocarriers for delivery of doxorubicin to enhance the activity and safety of these systems. Spherical AuNPs@PABA-QP obtained by facile and green synthesis under optimum conditions were characterized by UV-VIS, TEM, EDS, SAED, XRD, ATR-FTIR and zeta-potential analyses …
