Summary: The development of effective direct electron transfer for high performance bioelectrodes is an interesting platform. Designing scalable and cost-effective immobilization routes to promote correct direct electrical contacting between the electrode material and the redox enzyme is still necessary. Electrochemical entrapment of PQQ-GDH on SWCNT-modified electrodes enhances electrocatalytic activity towards glucose oxidation. Both entrapment of reconstituted holoenzyme and entrapment of apoenzyme followed by reconstitution show preservation of electrocatalytic activity towards glucose oxidation, with significantly enhanced sensitivity for glucose oxidation using lower amounts of enzyme and cofactor. Single-step electrochemical entrapment in presence of 4-APPA provides a simple method for enzymatic bioelectrode fabrication.

Summary: In this study, carbonaceous materials were synthesized from typha tassel (TT) and pussy willow (PW) as biomass sources for enzymatic electrode modification. Different immobilization strategies using the carbonized TT (CTT) and PW (CPW) together with glucose oxidase (GOx), ferrocene (Fc), and Chitosan (Chit) were investigated. The results showed that Chit could preserve the activity of GOx, and when Fc was co-immobilized with GOx, better performance was achieved. The prepared electrodes demonstrated promising results for glucose biosensing. This study provides a comprehensive investigation of different immobilization strategies of GOx on carbonaceous electrodes and explores the potential use of biomass materials in bioelectronics approaches.

Summary: Pyrroloquinoline quinone-dependent and flavin adenine dinucleotide-dependent enzymes catalyze the oxidation of various compounds, but the active sites embedded in the molecule make direct bioelectrocatalysis difficult. Researchers have attempted to connect electron transfer domains through protein engineering to achieve direct electron transfer. Recent reports have also shown enzymes without electron transfer domains are able to undergo direct electron transfer to an electrode.

Summary: Current techniques for the solid phase synthesis of molecularly imprinted polymer (MIP) nanoparticles often use amino silanes for template immobilization prior to polymerization. However, a study found that these amino silanes have problematic side reactions that negatively impact the purity and affinity of the polymers. In this case study, iodo silanes were proposed as a superior alternative and were used to successfully synthesize MIPs targeting epitopes of the cancer biomarker EGFR, showing higher purity, specificity, and nanomolar affinity for the target peptide.

Summary: Despite the environmental risks associated with nuclear power in public consciousness, it remains one of the cleanest, most efficient, and carbon-neutral energy sources. The development of nuclear energy is hindered by the challenge of handling spent nuclear fuel. The concept of a closed nuclear cycle has been proposed to address this issue, involving the efficient separation of minor actinides from other fuel components using N,O-hybrid donor ligands. This review explores the literature on this topic and provides detailed explanations of the behavior of promising ligands, as well as their application in chemical sensors.

Summary: Spectroscopic techniques in analytical chemistry play a crucial role in medical and biological research, particularly in cancer diagnosis, therapy, and surgery. However, the lack of an efficient and cost-effective real-time tumor margin assessment method results in a high rate of re-excision surgeries and overcrowding of medical facilities. Optical spectroscopy has been applied for intraoperative margins detection, with rapid spectra acquisition, a wide range of spectrometers and fiber optics, and minimal invasiveness. Given the growing number of papers in this field, it is important to summarize current achievements and future perspectives. This review focuses on the development of a spectroscopic tool for intraoperative margins assessment, with a specific emphasis on experimental designs and results of chemometric data analysis.
