Electrochemical sensing platform for the detection of methyl parathion applying highly biocompatible non-covalent functionalized phosphonium-based ionic liquid@MWCNTs hybrid to immobilize hemoglobin

Kaixin Liu et al.

Summary: A hydrophobic carboxyl functionalized phosphonium-based ionic liquid was synthesized and used to immobilize hemoglobin on multi-wall carbon nanotubes, creating an effective electrochemical sensing platform for detecting methyl parathion in vegetables. The platform showed improved sensitivity and performance, indicating the potential of phosphonium-based ILs for constructing electrochemical sensing interfaces.

Dynamics of camel and human hemoglobin revealed by molecular simulations

Amanat Ali et al.

Summary: This study investigates the behavior of camel hemoglobin under stress and compares it to human hemoglobin using molecular dynamics simulations. The results show that camel hemoglobin is more stable than human hemoglobin under physiological stress. Additionally, the cofactor-binding regions in human hemoglobin exhibit greater fluctuations compared to camel hemoglobin. The study also identifies differences in residues interacting with heme between camel and human hemoglobin.

Optical cytosensors for the detection of circulating tumour cells

Fereshteh Vajhadin et al.

Summary: Blood analysis is a well-established method for monitoring various diseases, including cancer. In recent years, the focus has shifted to the detection of circulating tumor cells (CTCs), which can provide valuable information about the cancer status. Optical cytosensors, such as colorimetry and fluorescence, have shown promising results in detecting CTCs. However, further research is needed to fully exploit their potential in cancer diagnostics and monitoring.

Hollow BiOBr/reduced graphene oxide hybrids encapsulating hemoglobin for a mediator-free biosensor

Hafiz Akif Munir et al.

Summary: The research utilized hollow BiOBr microspheres (H-BiOBr MS) and H-BiOBr/rGO hybrids synthesized via hydrothermal method as materials for mediator-free biosensors to immobilize hemoglobin. The hybrids showed larger specific surface area and better biocompatibility, leading to more stable and bioactive proteins. The modified electrode hybrids effectively improved the direct electron transfer of hemoglobin, resulting in wide linear range and low limit of detection for H2O2 biosensors.
