Summary: Template-patterned, flexible transparent electrodes (TEs) were formed using an ultrathin silver film on top of the commercial optical adhesive Norland Optical Adhesive 63 (NOA63). The NOA63 base-layer prevents coalescence of silver atoms, creating ultrasmooth continuous films. The combination of 12 nm silver films on NOA63 shows high visible-light transparency and low sheet-resistance, making them ideal for flexible TEs. Etching the NOA63 base-layer before silver deposition allows for the creation of insulating regions, resulting in a patterned TE for flexible devices.

Summary: A self-supported heterojunction catalyst, NiCo-OH@NixFeyO4 on Fe foam (FF), is in situ synthesized using two-step corrosion engineering, which can drive the current density of 1000 mA cm-2 with low overpotential of 275 mV and good long-term stability. The performance is attributed to electron transfer and weakened adsorption energy, promoting O2 release and reducing free energy barriers for the reaction. The study demonstrates the potential of the water splitting cell with NiCo-OH@NixFeyO4/FF as anode and CoP@FeP/FF as cathode for industrial applications, and presents a general strategy for in situ synthesis of heterojunction catalysts on metal foams.

Summary: In this article, the latest developments in biosensors for cancer cell detection are highlighted. Electrochemical (EC) biosensors provide advantages such as high sensitivity, selectivity, rapid analysis, portability, and low-cost. Different types of biosensors, including immunosensors, aptasensors, cytosensors, electrochemiluminescence (ECL), and photo-electrochemical (PEC) sensors, can be classified. The significance of EC biosensors lies in their ability to detect various biomolecules in the human body, including cholesterol, glucose, lactate, uric acid, DNA, blood ketones, hemoglobin, and others. Recently, EC biosensors have been developed using electrocatalytic materials such as Ag2S, BPene, HCNT, CDs/CoOOH, Cu2O, PDs, MnO2, graphene derivatives, and Au-NPs. These biosensors have shown potential for detecting cancer cells with a limit of detection (LOD) of 1 cell/mL. However, more real samples need to be tested to verify the accuracy and reliability of these EC biosensors in measuring cancer cells in blood and salivary samples.

Summary: The antimicrobial resistance crisis is a global health issue that requires the discovery and development of new therapeutic methods. Conventional screening methods for natural products or synthetic chemical libraries are uncertain. Combination therapy using approved antibiotics and inhibitors that target innate resistance mechanisms is an alternative strategy for developing potent therapeutics. This review discusses the chemical structures of effective beta-lactamase inhibitors, outer membrane permeabilizers, and efflux pump inhibitors that act as adjunct molecules to classical antibiotics. Rational design of adjunct chemical structures provides methods to enhance or restore the efficacy of classical antibiotics against inherently antibiotic-resistant bacteria. Simultaneously targeting multiple pathways with adjunct molecules shows promising approaches to combat multidrug-resistant bacterial infections.
