Summary: This study applies quantum biological tunnelling for electron transfer to control and treat cancer cells by triggering apoptosis through wireless nano-electrochemical tools. The experimental results show that electrical input can selectively trigger electron transport between redox molecules, leading to the elimination of cancer cells. This work demonstrates the potential of quantum-based medical diagnostics and treatments.

Summary: Effective monoclonal antibody (mAb) therapies require a specific serum concentration of mAbs to be effective and avoid side effects. This study used microporous nylon membranes functionalized with antibody-binding peptides to capture mAbs from diluted patient sera, allowing for quantitation using native fluorescence. Future work aims to develop rapid point-of-care devices and decrease detection limits for more successful treatments.

Summary: The study investigates the effect of immobilized ssDNA density on genetic diagnosis using AuNPs. Lower DNA densities improve the sensitivity of target ssDNA detection. Furthermore, the study finds that DNA density, rather than dispersion stability, significantly impacts the detection sensitivity.

Summary: This study presents an acousto-nanodevice that can oxidize redox proteins under ultrasonic irradiation. By using surface-engineered barium titanate (BTO) nanoparticles with a gold half-coating, the nanodevice is capable of modulating the redox proteins and enabling unidirectional electron transfer. This new class of ultrasonically powered nano-sized protein redox agents has the potential to be a highly selective modulator for biological processes with deeper treatment sites.

Summary: The present study synthesized a green functional material based on silver nanoparticles (Ag NPs) doped cellulose nanocrystals (CNC) immobilized agar gum (AA) biopolymer using the chemical coprecipitation method. Various spectroscopic techniques were used to analyze the stabilization of Ag NPs in the cellulose matrix and the functionalization of the synthesized material through agar gum. The material exhibited good photocatalytic activity for the degradation of malachite green (MG) in wastewater.

Summary: A label-free sensor based on SPR imaging was proposed to monitor nanoparticles in fresh water, with improved sensitivity by enhancing the detector and using LED excitation for the light source. Different self-assembled monolayers were screened as receptors, with the best system being a dodecanethiol monolayer on the gold sensor surface. The sensor successfully detected lanthanide-doped nanoparticles of 29 nm in water.

Summary: This study investigated the adsorption of lysozyme onto gold nanoparticles and obtained the free energy of binding of the system for the first time. The interactions between lysozyme and AuNPs induce aggregation of citrate-stabilized AuNPs at low concentrations. The study also found that 10 nm AuNPs were the most appropriate for this interaction.

Summary: A novel electrode platform for H2O2 detection was developed by immobilizing r-TOP on p-PD/MWCNTs/G modified graphite electrodes, enhancing sensitivity, stability, and selectivity while preventing enzyme inactivation due to the electro-Fenton reaction. The electrode exhibited a lower limit of detection of 1.8 mu M H2O2, an extended linear range between 6 and 900 mu M H2O2, and increased sensitivity compared to previous work based on TOP.

Summary: Three different macroalgae, U. lactuca, U. linza, and U. compressa, were studied for biological photovoltaic energy system (BPVE) using edge plane pyrolytic graphite as the working electrode. The biophotoanodes were evaluated for direct and mediated electron transfer processes using different mediators. The results showed that using p-benzoquinone (BQ) as a mediator during the mediated electron transfer process significantly increased the electron transfer to the graphite electrode during light conditions.
