“…F) and 2(G) show that the characteristic absorption peaks of PEA and HA can be observed on the corresponding site. Figures 2(F) and 2(G) also show the reduction of the characteristic absorption peaks of the carboxyl group (1,718 cm À1 ) on GO and HA and the characteristic absorption peaks of the amino group (2,970 cm À1 ) on PEA[39]. These findings indicate the successful synthesis of GO-PEA-HA.…”

A novel drug carrier was designed based on a new biomaterial, that is, graphene oxide (GO), to improve the efficiency and specificity of anticancer drug. In this study, GO was successively modified with polyetheramine (PEA) and hyaluronic acid (HA). The carrier was utilized to load an antitumor component, that is, quercetin (Que), which was derived from traditional Chinese medicine, namely the pagoda tree flower bud. This drug delivery system (DDS) exhibited pH sensibility under subacid condition and good biocompatibility even when GO concentration reached 350 μg/mL. Moreover, the antitumor efficacy was doubly improved and more long-acting compared with Que alone. Results show that the GO-based material has potential clinical applications for antitumor drug delivery.

“…The LOD was 0.07 ng/mL, with a wide dynamic range of 0.1-10 ng/ mL, for cTnI. 18 The Clinical Laboratory and Standards Institute defines the LOD as the minimum concentration of the analyte at which detection occurs. It helps in measuring the sensitivity of the sensor and determines the lower limit of the dynamic range over which the sensor operates.…”

The development of the methods for early and accurate diagnosis of acute myocardial infarction are needed to facilitate immediate treatment of patients. One of the ways to achieve that is the detection of cardiac biomarkers for myocardial infarction, such as thrombin, cardiac troponins (I and T), myoglobin, etc. Nanotechnology has played an important role in the development of sensitive and efficient electrochemical sensors for cardiac biomarkers. In this review, we discuss recent progress on nanomaterial‐based electrochemical sensing of various cardiac biomarkers for acute myocardial infarction.
