The main competitive advantages and professional competencies of LOX employees lie in the development of nanohybrid systems for use in medical diagnostics and optoelectronics. Having been established in 2011, based on a mega-grant received by Professor Igor Nabiev within the framework of the program of attracting leading scientists to Russian institutions of higher special education, the group is recognized as one of the most successful “Mega-grant” structures that continue to function effectively under the leadership of its leading scientist.
LOX staff were the first European scientists in the field of synthesis of fluorescent tags based on quantum dots (QDs) and their application in medicine [1, 2]. The created suspension chips for flow cytometry based on polymer microspheres encoded by QDs, as well as nanoprobes based on conjugates of single-domain antibodies (odATs) and QDs allow successful detection of serological and histological oncomarkers, such as CEA [3,4], HER2 [5], prostate-specific antigen PSA [6], as well as multiparametric serological detection of lung cancer oncomarkers [7]. The sensitivity of the obtained CT-based probes is so high that it allows the detection of individual cancer cells and micrometastases [8]. Application of the procedure of oriented conjugation of odAt and CT allows to create ultra-compact probes that easily penetrate tumor tissues and allow obtaining three-dimensional images [9-11]. CTs are also suitable for use in theranostic systems, providing controlled drug delivery to tumor tissues [12-14].
Among the main scientific results of the LOX staff in recent years, the following should be noted:
1. A unique setup for realization of the strong light-substance coupling mode for a wide class of compounds, including biological molecules and complexes, was created, patented and described:
