In vitro Evaluation of Carbon‐Based Nanospheres as Drug Delivery Vesicles in Breast Cancer Cell

Abstract

The application of nanoparticles in cancer treatment allows precise tumor treatment by enhancing drug delivery to the tumor area. To overcome limitations in the drug delivery system, we report carbon‐based nanospheres (CSs) that have high drug loading capacity as well as anti‐cancer effects. Monodisperse and size‐tunable (170–583 nm) CSs with excellent surface area up to 2619 m2/g provided high drug loading capacity in four different types of drugs (doxorubicin, gemcitabine, docetaxel, and paclitaxel), and demonstrated strong anti‐cancer effects against MDA‐MB‐231 human breast carcinoma cells.

High‐Performance Asymmetric Supercapacitors Based on Monodisperse CuO@C Polyhedron Nanocomposites

“…Monodisperse CS with size of 390 nm shows very high SSA of 3891 m 2 /g obtained from the BET model using nitrogen sorption isotherm and PSD derived from the BJH method up to 4 nm (Supporting Information Figure S9 and Table 1). 20,21 CV profiles of CS with various scan rates (10–200 mV/s) are displayed in the Supporting Information Figure S10 that quasi‐rectangular shape indicative of characteristic EDLC‐type capacitive property is clearly confirmed 24 . GCD profiles of CS with various current densities (1–50 A/g) present isosceles triangular shape, which is also characteristic EDLC feature and rate retention of CS is ca.…”

“…The samples were placed in an alumina boat in a quartz tube in the isothermal zone of a tubular furnace that was purged with flowing nitrogen. The samples were heated to 900 °C (heating rate 30 °C/min) under inert conditions (N 2 ), followed by changing the gas flux to CO 2 (1000 cc/min) for 720 min 20,21 …”
