Recent Improvements in CRISPR-Based Amplification-Free Pathogen Detection

open access: yesFrontiers in Microbiology, 2021
Molecular diagnostic (MDx) methods directly detect target nucleic acid sequences and are therefore an important approach for precise diagnosis of pathogen infection. In comparison with traditional MDx techniques such as PCR, the recently developed CRISPR-

Prospects of Microfluidic Technology in Nucleic Acid Detection Approaches

open access: yesBiosensors, 2023
Conventional diagnostic techniques are based on the utilization of analyte sampling, sensing and signaling on separate platforms for detection purposes, which must be integrated to a single step procedure in point of care (POC) testing devices.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
