“…[33,34] Meanwhile, we combined the layered double hydroxide multi-nanosheets NiM-LDH (Figure S12) with cMOF Ni-HHTP and successfully synthesised NiM-LDH@Ni-HHTP to explore the synergistic effect between Ni 2 + and different metal ions in glucose detection. [35][36][37] On one hand, to examine the impact of varying dosages of Ni(OAc) 2 • 4H 2 O and Co(OAc) 2 • 4H 2 O on the structural characteristics of cMOF, we gradually increased the dosage of Ni-(OAc) 2 • 4H 2 O in Ni(OH) 2 @NiCo-HHTP-1~4 samples, and in Ni-(OH) 2 @NiCo-HHTP-5~7 samples, we gradually increased the Co(OAc) 2 • 4H 2 O dosage, while only Co(OAc) 2 • 4H 2 O was added in the Ni(OH) 2 @Co-HHTP samples (Table S3). It can be observed that the density of the cMOF nanorods on the Ni(OH) 2 surface progressively augments with the increment of Ni(OAc) 2 • 4H 2 O (Figure S13a1-a4).…”

Glucose holds significant importance in disease diagnosis as well as beverage quality monitoring. The high‐efficiency electrochemical sensor plays a crucial role in the electrochemical conversion technology. Ni(OH)2 nanosheets are provided with high specific surface area and redox activity that are widely used in electrochemistry. Conductive metal‐organic frameworks (cMOFs) perfectly combine the structural controllability of organic materials with the long‐range ordering of inorganic materials that possess the characteristic of high electron mobility. Based on the above considerations, the combination of Ni(OH)2 and Ni‐HHTP (HHTP = 2,3,6,7,10,11‐hexahydroxytriphenylene) as an electrode modification material is designed to enhance electrochemical performance. In this work, to improve glucose detection, a sequence of Ni(OH)2@NiCo‐HHTP and NiM‐LDH@Ni‐HHTP (M = Co2+, Mn2+, Cu2+, LDH = layered double hydroxide) are successfully synthesised by doping metals into Ni‐HHTP and Ni(OH)2, respectively. As a result, NiCu‐LDH@Ni‐HHTP showed the best excellent glucose detection sensitivity.

“…This method involves repetitive seeding and growing cycles or simply adjusting the number of used seeds. 148 Due to their comparable crystal structures and lattice constants, it is possible to epitaxially grow MOF shells on another MOF seed successfully. This method allows for the full integration of MOF advantages, leading to substantial synergistic effects.…”

“…17 In general, TiN and Cu-Au NPs are promising to be useful in several fields such as catalysis, light harvesting, optoelectronics, and biotechnologies. [25][26][27][28][29][30] We assess the biotesting LFA-performance of three different NPs (Fig. 1B) and show that inexpensive plasmonic TiN-and Cu@Au-based LFAs perform comparable to Au NPs-based LFAs, in some cases even better.…”

Different kinds of nanoparticles can be conjugated with diverse biomolecular receptors and employed in biosensing to detect a target analyte (biomarkers of infections, cancer markers, etc.) from biological samples. This proven concept was largely used during the COVID-19 pandemic in over-the-counter gold nanoparticles-based paper strip tests. Considering that gold is expensive and is being largely depleted, here we show that novel and less expensive plasmonic counterparts, titanium nitride (TiN) nanoparticles, and copper nanoparticles covered with a gold shell (Cu@Au) perform comparable or better than gold nanoparticles. After functionalization, these novel nanoparticles provide a high signal, efficiency, and specificity when used on paper strip tests. This allows an easy visual determination of the positive signal and the development of more affordable paper-based test strips. Moreover, by conducting the machine learning study, we have shown that the bio-detection with TiN is more accurate than that with gold, demonstrating the advantage of a broadband plasmonic material. The implementation of lateral flow assays based on TiN and Cu@Au nanoparticles promises a drastic cost reduction of this technology and its widespread applications in tasks of biomedical diagnostics, environmental and food safety, security and doping screening.
