z-LAB是一套完整的，实时的，免标记生物科学设备，用于分析生物体表面阻抗及深度阻抗。 z-LAB阻抗分析仪为研究分子薄膜提供一个新的解决方案，包括对于分子薄膜表面覆盖，组织结构，传输转移现象 z-LAB offers high sensitivity and fast acquisition of data by monitoring real-time impedance changes at the sensor–solution interface. 阻抗数据包括电容和电阻，基于共振辅助表面阻抗技术 Resonance Enhanced Surface Impedance (RESI) ，这使得比较复杂的分子薄膜得以解释。 This makes it possible to follow complex molecular events that cannot be detected using conventional impedance spectroscopy, masssensitive acoustic or optical techniques. 应用领域包括：蛋白质，脂质体，表面活性剂，高分子及纳米颗粒等表面相互作用。
实时电容和电阻分析 The capacitance reflects the surface coverage and structural state of thin molecular films. The formation and organisation of a surface film (e.g. protein adsorption) can be monitored by following the change in capacitance and resistance over time. The resistance reflects charge-transfer processes across the interface. Small changes in resistance, due to for example ion transport via incorporated pores in an adsorbed film, can be detected as they occur in real-time.
测试表面覆盖性能 Track layer formation on the sensor surface, including molecular films, self-assembled monolayers, lipid bilayers and nanoparticle arrays.
分析分子层每层的组织结构 Measure the electrical properties at interfaces to gain information about the level of molecular density and organisation.
监测电量转移 Study charge-transfer across surface layers, iontransporter functionality in lipid bilayers and monitor redox-reactions.
免标记分子相互作用分析 Real-time recording of biomolecular interactions, e.g. receptor-ligand binding.
