Self-assembled sugar-based copper nanoparticles as trimethylamine sensor

Hybrid hydrogels derived from renewable resources as a smart stimuli responsive soft material for drug delivery applications

“…Recently, we have reported the synthesis and self-assembly of cardanol-based functional molecules and explored their potential applications in the eld of biomaterials and electronics. [32][33][34][35][36][37] The excellent antioxidant property and selfassembling characteristics of largely explored fatty acid amides elicited us to design and synthesize the amphiphilic N-acyl amides from cardanol and amino alcohols such as propanol amine 4, tris 5, and dopamine 8. Amphiphilic N-acyl amides (6, 7) bearing aliphatic OH group as a hydrophilic moiety were synthesized via the nucleophilic substitution of 3-alkyl phenols 1a,b with methyl bromoacetate 2, followed by amidation with amino alcohols 4, and 5 (Scheme 1).…”

“…By having amphiphilic N-acyl amides bearing various degree of hydrophilic groups, we further moved on investigating the gelation efficiency in various solvents and vegetable oils using the "stable to inversion" method. [32][33][34][35][36][37][38][39][40] Most interestingly, compounds 6a and 7a displayed oleogelation in light paraffin oil with the critical gelation concentration (CGC) of 1.0 and 0.9% (w/v) respectively. In addition, compounds 6a and 7a also formed organogel in PEG with a CGC of 1.0 and 0.85% (w/v), and hybrid hydrogel in water-DMSO (3 : 1) with a CGC of 1.3% (w/v) and 1.0% (w/v) respectively (Table 1).…”

“…Generally, aggregation of a gelator to generate supramolecular architecture in micro or nanoscale is based on the molecular structure of the gelator, solvent used, temperature and pressure. [32][33][34][35][36][37][38][39][40][41][42] However, properties of so materials were governed by the molecular assembly, which requires a clear understanding across length scales controlled by intermolecular interactions.…”

“…In particular, a deep insight into a ow and viscoelastic behaviour of a so material, which belongs to a unique category neither behave like ideal solid and nor ideal liquid were obtained by measuring the storage modulus G 0 (elastic) and the loss modulus G 00 (viscous) in response to the strain. [32][33][34][35][36][37]50,51 Such an interesting deformation of a so material in response to stress or strain is due to the internal morphology drew up with the supra-molecular arrangement of small or macromolecules and colloidal organic/inorganic particles. However, till to date there is no direct correlation were derived between the internal morphology and viscoelastic behaviour of so materials, in particular, many of the questions related to the micro/ nanostructure and viscoelastic behaviour remain unanswered.…”

A MOF-derived porous In2O3 flower-like hierarchical architecture sensor: near room-temperature preparation and fast trimethylamine sensing performance

“…It emits unpleasant fishy smell at low concentration and ammonia-like smell at high concentration. 1,2 It can irritate eyes and harm the respiratory tract. It may cause diseases such as headache, nausea, vomiting, cough and other symptoms.…”
