Intrinsic Chirality Modulation and Biosensing Application of Helical Gold Nanorods by Anisotropic Etching.

The investigation of plasmonic chirality is a profound and intriguing topic, and the distinctive morphology of intrinsically chiral nanoparticles has prompted significant interest in the structure-activity relationship between particle morphology and chirality. In this work, the anisotropic etching of chiral helical gold nanorods (HGNRs) by a cetyltrimethylammonium bromide (CTAB)-HAuCl complex was observed with an interesting bidirectional variation of intrinsic chirality that initially enhanced and subsequently weakened, which was related with the diversity in CTAB distribution. In addition, an ultrasensitive and convenient sensing platform for acetylcholinesterase was developed based on the circular dichroism signal recovery of HGNRs caused by the dual inhibition of HGNR etching.

Amifostine-Loaded Nanocarrier Traverses the Blood-Brain Barrier and Prevents Radiation-Induced Brain Injury.

Radiation-induced brain injury (RIBI) is a severe, irreversible, or even life-threatening cerebral complication of radiotherapy in patients with head and neck tumors, and there is no satisfying prevention and effective treatment available for these patients. Amifostine (AMF) is a well-known free radical scavenger with demonstrated effectiveness in preventing radiation-induced toxicity. However, the limited permeability of AMF across the blood-brain barrier (BBB) when administered intravenously reduces the effectiveness of AMF in preventing RIBI.

Inhibition of colon cancer K-Ras mutation reduces cancer cell proliferation but promotes stemness and inflammation RAS/ERK pathway.

K-Ras is a well-studied oncogene, and its mutation is frequently found in epithelial cancers like pancreas, lung, and colorectal cancers. Cancer cells harboring K-Ras mutations are difficult to treat due to the drug resistance and metastasis properties. Cancer stem cells (CSCs) are believed the major cause of chemotherapeutic resistance and responsible for tumor recurrence and metastasis.

"Hepatitis virus indicator"----the simultaneous detection of hepatitis B and hepatitis C viruses based on the automatic particle enumeration.

As the common hepatitis viruses, hepatitis B virus (HBV) and hepatitis C virus (HCV) are important causes of liver diseases, which greatly threaten human health and public hygiene. Furthermore, due to the similar transmission routes of HBV and HCV, it is highly susceptible to suffer from the cross-infection of HBV and HCV when humans are infected by hepatitis viruses. So it is urgent to develop strategies with high sensitivity to distinguish HBV/HCV and detect their overlapping infection.
