A photoelectrochemical aptasensor based on double Z-scheme α-FeO/MoS/BiS ternary heterojunction for sensitive detection of circulating tumor cells.

A novel photoelectrochemical (PEC) aptasensor based on a dual Z-scheme α-FeO/MoS/BiS ternary heterojunction for the ultrasensitive detection of circulating tumor cells (CTCs) was developed. The α-FeO/MoS/BiS nanocomposite was prepared via a step-by-step route, and the photoproduced electron/hole transfer path was speculated by conducting trapping experiments of reactive species. α-FeO/MoS/BiS-modified electrodes exhibited greatly enhanced photocurrent under visible light due to the double Z-scheme charge transfer process, which met the requirement of the PEC sensor for detecting larger targets.

Integrated ultra-high pressure and salt addition to improve the in vitro digestibility of myofibrillar proteins from scallop mantle (Patinopecten yessoensis).

Myofibrillar protein (MP) is susceptible to the effect of ionic strength and ultra-high pressure (UHP) treatment, respectively. However, the impact of UHP combined with ionic strength on the structure and in vitro digestibility of MP from scallop mantle (Patinopecten yessoensis) is not yet clear. Therefore, it is particularly important to analyze the structural properties and enhance the in vitro digestibility of MP by NaCl and UHP treatment.
