Most biosensors relying on antibodies as recognition elements fail in harsh environment conditions such as elevated temperatures, organic solvents or proteases because of antibody denaturation, and require strict storage conditions with defined shelf-life, thus limiting their applications in point-of-care and resource-limited settings. Here, a metal-organic framework (MOF) encapsulation is utilized to preserve the biofunctionality of antibodies conjugated to nanotransducers. This study investigates several parameters of MOF coating (including growth time, surface morphology, thickness and precursor concentrations) that determine the preservation efficacy against different protein denaturing conditions in both dry and wet environments. A plasmonic biosensor based on gold nanorods as the nanotransducers is employed as a model biodiagnostic platform. The preservation efficacy attained through MOF encapsulation is compared to two other commonly employed materials (sucrose and silk fibroin). The results show that MOF coating outperforms sucrose and silk fibroin coatings under several harsh conditions including high temperature (80 °C), dimethylformamide and protease solution, owing to complete encapsulation, stability in wet environment and ease of removal at point-of-use by the MOF. We believe this study will broaden the applicability of this universal approach for preserving different types of on-chip biodiagnostic reagents and biosensors/bioassays, thus extending the benefits of advanced diagnostic technologies in resource-limited settings.

“…For a good catalytic performance of Co, pyrrolic or Co bonded N seems to be crucial . In addition, the Co contents of MOFs have been shown to promote the formation of highly graphitic frameworks even at low temperatures . The outstanding electrical conductivity of graphene can greatly promote the electron transfer, which enhances the electrochemical response towards the oxidation of dopamine .…”

Co/Co‐N nanoparticles incorporated nitrogen‐doped nanoporous carbon (Co/Co‐N@NPC) nanostructures were fabricated via pyrolysis of metal organic framework, ZIF‐67, under argon atmosphere. The ZIF‐67 derived Co/Co‐N@NPC modified carbon paste electrode exhibited excellent performance during electroanalysis of dopamine, displaying two linear ranges; 10 nM to 50 μM, and 50 μM–500 μM with sensitivity of 12.4±0.3 μA/μM/cm2 and11.69±0.06 μA/μM/cm2, respectively. The modified electrodes were observed to be highly selective towards dopamine even in presence of other interfering biomolecules such as ascorbic acid, glucose and uric acid. To the best of our knowledge, the sensing ability of Co/Co‐N@NPC with a lower limit of detection as 6 nM is the best compared to the previously reported cobalt mediated sensors for dopamine. Practical feasibility of the sensor was demonstrated in real sample analysis of dopamine measurement in human urine samples and dopamine hydrochloride injection samples.

Lead-based primary explosives were widely applied in military and civilian ammunition, which have subsequently caused serious environmental and health-related problems. Therefore, the development of green alternatives for the lead-based primary explosives has been one of the major focuses in the field of energetic materials. Four potassium salts based on nitraminofurazan have been easily synthesized and show excellent comprehensive performances. Among them, potassium 3-dinitromethyl-4-nitraminofurazan (K DNMNAF, 1) showed better thermal stability (T : 281.4 °C), higher density (2.174 g cm ), and lower friction sensitivities (72 N) than that of potassium 4,5-bis(dinitromethyl)furoxanate (K BDNMF, T : 218.3 °C, density: 2.130 g cm , FS: 5 N, P: 27.3 GPa, v : 7759 m s ); furthermore, it displayed comparable detonation performances (P: 27.2 GPa, v : 7758 m s ). The promising properties of these salts make this kind of material a competitive alternative to lead azide as a primary explosive.
