Ultrarapid and ultrasensitive detection of SARS‐CoV‐2 antibodies in COVID‐19 patients via a 3D‐printed nanomaterial‐based biosensing platform [PDF]

open access: yesJournal of Medical Virology, Volume 94, Issue 12, Page 5808-5826, December 2022., 2022
Abstract Rapid detection of antibodies during infection and after vaccination is critical for the control of infectious outbreaks, understanding immune response, and evaluating vaccine efficacy. In this manuscript, we evaluate a simple ultrarapid test for SARS‐CoV‐2 antibodies in COVID‐19 patients, which gives quantitative results (i.e., antibody ...

N protein‐based ultrasensitive SARS‐CoV‐2 antibody detection in seconds via 3D nanoprinted, microarchitected array electrodes [PDF]

open access: yesJournal of Medical Virology, Volume 94, Issue 5, Page 2067-2078, May 2022., 2022
Abstract Rapid detection of antibodies to SARS‐CoV‐2 is critical for COVID‐19 diagnostics, epidemiological research, and studies related to vaccine evaluation. It is known that the nucleocapsid (N) is the most abundant protein of SARS‐CoV‐2 and can serve as an excellent biomarker due to its strong immunogenicity.

Borehole TV Imaging Technology for Horizontal Directional Drilling Based on an Optimization Algorithm for Structural Planes

open access: yesAdvances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023
The horizontal directional drilling technology combined with the borehole TV imaging technology can be used to obtain most of the geological information in conventional adit exploration. This combination has little impact on the environment and is free from topographic constraints, thus contributing to green exploration.
