The project “Molecular Design of New Fluorescent Compounds for Diagnostic Purposes” will carry out interdisciplinary fundamental nature studies, which will provide synthesis of new fluorescent dyes for various diagnostic purposes. The aim of the project is to synthesise new luminophores for diagnosis of diseases in medicine and veterinary medicine. The use of new synthesised dyes opens up new opportunities for the development of innovative non-invasive, early and express-diagnostics on a global scale. The first stage involves the development of new fluorescent dyes (development of more optimal synthesis methods), characterisation and research of spectral parameters related to biological objects (human blood cells, animal and parasite fabrics, etc.). In the second stage, the aprobation of synthesised dyes and the establishment of protocols will take place. The aim of the project will be achieved in collaboration with several scientific institutions, applying a complex of chemistry, parasitology, histology, physics, genomics, and clinical methods. It will also set up a number of working groups covering today’s important diagnostic areas in medicine, veterinary and biology. Research results will focus on the prototype of a new product and the development of protocols for new innovative methods (e.g. histology, karyotyping parasitology, etc.). Synthesised sensory luminophores, developed innovative methods and protocols will be significant at Latvian and European level even after the end of the project. The implementation of this project would address significant problems in various fields of diagnosis and research. Keywords: Fluorescent dyes, synthesis, innovative express diagnosticsThe aim of the project is: Synthesise new luminophores for diagnosis of diseases in medicine and veterinary medicine. The project provides for fundamental research. The project is not related to economic activities.Project fields of science: Chemical sciences (1.4 FOS classification), clinical medicine (3.2), veterinary sciences (4.3). The new interdisciplinary project will involve 6 scientists (including three young), 6 doctoral students, 4 master students and students, as well as two state scientific institutions. The study is divided into four scientific research activities. The main planned activities of the project are:1. Co-ordination of the project – says from 01.03.2017.2. Molecular design of new luminophores:2.1. Development of new luminophores synthesis methods – implemented throughout the project period from 01.03.2017. to 29.02.2020.2.2. Investigation of the spectral properties of synthesised compounds – will link from 01.04.2017 to 29.02.2020.3. Cytogenetic diagnostics and research:3.1. Preparation of samples for karyotyping – will take place throughout the project period from 01.03.2017 to 29.02.2020.3.2. Fluorescence in situ hybridisation (FISH) – compresses from 01.06.2017 to 29.02.2020.4. Parasitic and histological diagnostics and research:4.1. Preparation of microscopy preparations – is implemented throughout the project from 01.03.2017. to 29.02.2020.4.2. Preparation microscopy – will say from 01.06.2017 to 29.02.2020.5. Characterisation of the microviscosity of plasma albumins and cell membranes – is realised throughout the project period from 01.03.2017 to 29.02.2020.6. Development of scientific articles and monographs, participation in international scientific conferences, organisation of seminars – is implemented throughout the project from 01.03.2017. to 29.02.2020.7. Patenting of results – will take place 1.06.2019.-29.02.2020.As a result of the project, methods of synthesis of new fluorescent dyes will be developed, from which the most promising luminophores for biomedical research will be selected. Research results will be concentrated in the development of protocols of new innovative methods in histology, karyotyping, parasitology, etc. Publish at least six scientific publications in existing scientific journals of Web of Science and/or SCOPUS databases, three publications in Web of Science or SCOPUS databases in magazines or conference articles, prepare one monograph on the studied colours and apply for at least two Latvian wide patents. The planned implementation period of the project is from 01.03.2017 to 29.02.2020 The total cost of the project is EUR 580000, of which 85 % (EUR 493000) support from the European Regional Development Fund.
