The growing prevalence of counterfeit products worldwide poses serious threats to economic security and human health. Developing advanced anti-counterfeiting materials with physical unclonable functions offers an attractive defense strategy. Here, we report multimodal, dynamic and unclonable anti-counterfeiting labels based on diamond microparticles containing silicon-vacancy centers. These chaotic microparticles are heterogeneously grown on silicon substrate by chemical vapor deposition, facilitating low-cost scalable fabrication. The intrinsically unclonable functions are introduced by the randomized features of each particle. The highly stable signals of photoluminescence from silicon-vacancy centers and light scattering from diamond microparticles can enable high-capacity optical encoding. Moreover, time-dependent encoding is achieved by modulating photoluminescence signals of silicon-vacancy centers via air oxidation. Exploiting the robustness of diamond, the developed labels exhibit ultrahigh stability in extreme application scenarios, including harsh chemical environments, high temperature, mechanical abrasion, and ultraviolet irradiation. Hence, our proposed system can be practically applied immediately as anti-counterfeiting labels in diverse fields.

“…The manufacturing of one-dimensional diamond nanoneedle structures can be classified into three main approaches: bottom-up techniques such as CVD, top-down techniques such as RIE, or other emerging techniques such as CVD method combined with thermal oxidation processes. − The limitations of each method dictate that the nanoneedles that can be fabricated vary in dimensionality and geometric aspect ratios.…”

Metrics & MoreArticle Recommendations * sı Supporting Information CONSPECTUS: Diamond nanomaterials have attracted significant interest in recent years due to their unique physical and chemical properties. Their exceptional mechanical strength, chemical stability, biocompatibility, and high thermal conductivity make them ideal candidates for a wide range of biomedical applications. Various formats, including nanodiamonds, diamond nanofilms, and diamond nanoneedle arrays (DNNAs), have been fabricated and used, exhibiting remarkable stability and low cytotoxicity. In particular, high-aspect-ratio and highdensity DNNAs demonstrate promising potential for live cell manipulation and analysis because of their unique combination of mechanical robustness, chemical stability, and wellforged bio−nanointerfaces. On the other hand, the chemical stability of diamond material makes fabrication and functionalization challenging, which could be improved for their wider adoption.Recent research efforts have focused on the development and optimization of diamond nanoneedle fabrication techniques, aiming to achieve precise control over the geometry and array layout, as well as enhancing their functionalization for targeted drug delivery, cellular manipulation, and biosensing applications. One notable breakthrough in this area is the successful synthesis of well-ordered DNNAs through innovative fabrication processes, such as combining top-down and bottom-up approaches. These efforts have led to significant improvements in the uniformity, reproducibility, and scalability of the resulting nanoneedle structures.Leveraging their unique structure, diamond nanoneedle arrays have become a novel and versatile platform for a variety of biomedical applications. Through chemical modifications and biological functionalization of their surfaces, DNNAs offer a distinct biointerface capable of penetrating cell interiors and profiling intracellular molecules without compromising cell integrity. Furthermore, the nanoscale distribution of these nanoneedles enables DNNAs to gather heterogeneous information from biological samples with spatial resolution. Consequently, DNNAs have been effectively utilized in diverse areas, ranging from targeted drug delivery to highly sensitive and selective biosensing.In this Account, we summarize our continuous efforts on utilizing bias-assisted plasma etching for the fabrication of high-aspect-ratio DNNA, which was subsequently functionalized and integrated as a generally applicable platform technology for various biomedical applications. The summary starts by elucidating the working principles of DNNA fabrication with bias-assisted plasma etching, followed by showcasing numerous biomedical applications. Specifically, we demonstrate the outstanding performance of DNNAs in live cell manipulation, especially for highly efficient intracellular delivery across multiple cell types, high-throughput intracellular molecular tracking in living cells, and spatiotemporal transcriptomic mapping in disease models.
