“…Here, we employed the alumina membranes to create the Au–Pt nanorods, using a two-step anodization of the aluminum sheets using oxalic acid as an electrolyte. The elimination of the aluminum oxide in the first step leaves a pattern, enabling the growth of nanochannel perpendicular to the surface in the second step in a more uniform manner . The remaining aluminum layer was removed via the acidic solution of CuCl 2 , creating AlCl 3 and metallic copper.…”

Further, to open both ends of channels and increase the diameter of the nanopores, the resulting membrane was immersed in phosphoric acid.…”

Researchers have been exploring the use of nanomotors powered by hydrogen peroxide for cancer treatment through targeted drug delivery. Asymmetric bimetallic nanorods made of platinum and gold have been found to navigate through the H 2 O 2 environment quickly and effectively, making them a promising option for the delivery of drugs to specific areas. We developed a delivery system for the hydroxyethyl disulfiram (DSF−OH) anticancer prodrug using a bimetallic Au/Pt nanomotor that moves toward its target in the presence of hydrogen peroxide. A copolymer consisting of poly(polyethylene glycol methyl ether methacrylate)-co-poly acrylic acid was used to conjugate the drug. The conjugate was then attached to the nanomotor's gold (Au) component using the sulfur moieties present in the DSF. The 1 H NMR, 13 C NMR, TGA, and FT-IR analyses confirmed the successful synthesis of the copolymer, whereas the SEM, EDX, XRD, and DLS analyses confirmed the production of the bimetallic nanomotor. Hydroxyethyl disulfiram (DSF−OH) was found to have different complex formation capabilities and time-dependent stabilities in comparison to disulfiram (DSF). It is suitable for prolonged drug release evaluations. UV−vis analysis evaluations showed around 34% of the released DSF− OH from the nanomotors. Particle tracking revealed a correlation between H 2 O 2 concentration and particle motion, indicating that higher H 2 O 2 concentration results in higher velocity and mean-square displacements (MSDs). MTT assays further validated superior selectivity and toxicity of drug-containing nanomotors toward MCF-7 breast cancer cells compared to L929 fibroblast cells. These findings have implications for drug delivery systems and provide insight into designing more efficient systems.

Eukaryotic cells possess the remarkable ability to sense and respond to mechanical cues from their extracellular environment, a phenomenon known as mechanobiology, which is crucial for the proper functioning of biological systems. Micropillars have emerged as a prominent tool for quantifying cellular forces and have demonstrated versatility beyond force measurement, including the modulation of the extracellular environment and the facilitation of mechano‐stimulation. In this comprehensive review, innovative strategies in micropillars’ design, fabrication, characterization, and biosensing applications are explored. The review begins with a foundational overview of micropillar‐based cell mechanobiology studies to provide a complete understanding, and then it delves into novel methodologies within each domain. The latter part of the review unveils innovative micropillars’ applications beyond mechanobiology, such as their use in enhancing biosensing surfaces and as upstream fluid manipulators for biosensors. Finally, in this review, future research directions are discussed and the current limitations of these techniques are outlined. Despite the extensive exploration of micropillar applications, a significant gap remains between research advancements and the practical implementation of micropillars in point‐of‐care diagnostics. Bridging this gap is crucial for translating laboratory innovations into real‐world medical and diagnostic tools.
