WebJun 30, 2024 · Special Issue Information. Dear Colleagues, Electronic noses and tongues, analytical devices based on an array of partially selective chemical sensors or biosensors and multivariate data processing tools, are often called biomimetic sensor systems or arrays as their design was inspired by biological sensing systems, primarily olfaction. WebBiomimetic HPLC is based mainly on stationary phases that mimic environment of a lipid membrane and they can be used in the assessment of interactions between molecules and biological membranes or for the estimation of permeability through cell membranes. The best model mimicking these natural processes is the liposomes.
WebTo achieve selectivity, significant inspiration for nanoparticle design can come from the geometric and molecular features that make enzymes selective catalysts. The two central features enzymes use are control over the arrangement of atoms in the active site and the placing of the active site down a nanoconfined substrate channel.
