摘要

利用无酶显微传感器测定生物材料的诊断性重要成分是一项紧迫的科学任务,世界上许多科学团体正在开展这项工作。这是由于惰性表面上的微小传感器主动轨迹可以在没有精密模板的初步制造的情况下获得。激光诱导化学液相沉积(llcd)是一种激光技术,它允许在激光束的焦点处从过渡金属化合物的水溶液中沉积微尺寸的导电轨迹。这些轨迹可以由一种或两种金属同时形成。在溶液中获得两种不同金属与配体的一个共同配位球相互作用的配合物的可能性特别令人感兴趣。这种配合物的结构还没有得到充分的研究。目前的研究补充了酒石酸配合物的缺失信息,酒石酸配合物可以同时配位两种金属,例如铜、镍、银、铁和钴。异相llcd在葡萄糖和过氧化氢的电化学氧化/还原中表现出高的感觉活性。双金属矿床可通过两种方式获得。第一种方法包括从含有一种金属离子的溶液中连续沉淀,然后在第一种金属离子的基础上再沉淀另一种金属离子。第二种方法是创造一种溶液,其中两种金属和一种配体同时存在。激光沉积是一次完成的。在实践中,第二种方法的可能性并不总是被实现。本文分析了表面高度发达的异相双金属传感器敏感多孔材料在激光辐射作用下形成的基本原理,为含两种金属酒石酸盐配合物的结构积累了新的参考数据。

The correlation between the structures of bimetallic tartrate complexes in solutions for laser-induced synthesis and sensor characteristics of microbiosensors materials
Determination of diagnostically significant components of biological materials using enzyme-free microscopic sensors is an urgent scientific task, which is being worked on by a significant number of scientific groups in the world. This is due to the fact that microscopic sensor-active tracks on inert surfaces can be obtained without preliminary manufacturing of precision templates. Laser Induced Chemical Liquid Phase Deposition (LCLD) is a laser technology that allows the deposition of microsized conductive tracks from aqueous solutions of transition metal compounds at the focus of a laser beam. These tracks can be formed by one or two metals at the same time. The possibility of obtaining complexes in solution in which two different metals interact with one common coordination sphere of the ligand is of particular interest. The structure of such complexes is still insufficiently studied. The present study supplements the missing information on tartaric acid complexes, which can simultaneously coordinate two metals, for example, copper, nickel, silver, iron, and cobalt. Heterophase LCLD demonstrates high sensory activity in the electrochemical oxidation/reduction of glucose and hydrogen peroxide. Bimetallic deposits can be obtained in two ways. The first method consists of successive precipitation from a solution containing an ion of one metal, then another on top of the first. The second way is to create a solution in which two metals and one ligand are simultaneously present. Laser deposition is carried out in one stage. In practice, the possibility of the second method is not always realized. In the present work, the basic principles of the formation of heterophase bimetallic sensor-sensitive porous material with a highly developed surface under the action of laser radiation have been analyzed, and new reference data have been accumulated on the structure of tartrate complexes containing two metals.

期刊介绍: Current Organocatalysis is an international peer-reviewed journal that publishes significant research in all areas of organocatalysis. The journal covers organo homogeneous/heterogeneous catalysis, innovative mechanistic studies and kinetics of organocatalytic processes focusing on practical, theoretical and computational aspects. It also includes potential applications of organocatalysts in the fields of drug discovery, synthesis of novel molecules, synthetic method development, green chemistry and chemoenzymatic reactions. This journal also accepts papers on methods, reagents, and mechanism of a synthetic process and technology pertaining to chemistry. Moreover, this journal features full-length/mini review articles within organocatalysis and synthetic chemistry. It is the premier source of organocatalysis and synthetic methods related information for chemists, biologists and engineers pursuing research in industry and academia.
