Summary: Optical chemosensors and ionochromic cellulosic papers based on oxazolidine chromophores were developed for selective photosensing of metal ions and information encryption as security tags. Oxazolidine molecules showed intense fluorescent emission and coloration characteristics, making them suitable for sensing and anticounterfeiting applications. The ionochromic cellulosic papers can be used for easy and fast photodetection of metal ions.

Summary: This article provides a synopsis of a case in which Amazon settled with two dupe influencers who used social media to promote counterfeit luxury products. The article emphasizes the challenges of selling luxury counterfeits online, consumer complicity in purchasing fake luxury goods, and the difficulty of discerning genuine products from counterfeits. Recommendations for combating dupe influencers include monitoring and collaboration with e-commerce platforms, raising consumer awareness, using legitimate influencers to debunk fakes, and pursuing legal action.

Summary: Counterfeit dominance negatively affects the perceived quality and purchase intention of luxury fashion brands for Anglo-American consumers, but not for Asians. This effect is mediated by perceived quality. The study contributes to both theory and practice by examining this understudied phenomenon and offering strategies to offset the negative impacts of counterfeit dominance.

Summary: This study evaluates the performance of a physical unclonable function (PUF) using Al2O3/TiOx based memristors. The wider distribution of high-resistance state (HRS) than low-resistance state (LRS) in PUF is confirmed through a conduction mechanism analysis. Additionally, cycle-to-cycle variation and random telegraph noise (RTN) characteristics impacting the reliability of the PUF are analyzed.

Summary: There is a strong demand for encoded surfaces with multiple security layers that are prepared by stochastic processes and are adaptable to deterministic fabrication approaches. Dewetting instabilities in nanoscopic polymer films present a suitable platform for fabricating unclonable surfaces, with the thermal annealing-induced dewetting of P2VP enabling fabrication of randomly positioned functional features that are separated at a microscopic length scale. The patterning of P2VP films presents opportunities for fabricating hybrid security labels, which can be resolved through both stochastic and deterministic pathways, offering key opportunities in encoding applications.

Summary: Biocompatible and flexible optical PUF labels have been developed by embedding microdiamonds in silk fibroin films, providing protection against counterfeit products and complex shaped objects. The silk fibroin films serve as a flexible and biocompatible substrate, while the Raman signal of the microdiamonds acts as the response mechanism, ensuring high stability and random distribution of PUFs with a maximum encoding capability of 2(10000). The cytotoxicity analysis results confirm the biosafety of the PUF system, and the labels have shown promising practical applications on various surfaces including polyethylene material, human skin, and even implanted under chicken skin tissue.
