The development of interdisciplinary fields in various sciences and emerging technologies in the field of medicine, including disease diagnosis (such as biosensors) and disease treatment (including tissue engineering, cell therapy, and gene therapy), is among the objectives of the Biology Department at the University of Maragheh. Another active research objective and area in the Biology Department is the optimization of producing valuable products and metabolites from various plant (especially medicinal and aromatic plants) and algal sources. Techniques such as plant cell, tissue, and organ culture in vitro, laboratory cultivation of algae, extraction techniques for active compounds from medicinal and aromatic plants, analysis of compounds in plants and algae using chromatographic and electrophoretic techniques (such as HPLC, GC-MS, SDS-PAGE, etc.), as well as molecular methods and techniques, are used to optimize the production of plant and algal metabolites. The establishment of the Phycolab (a specialized laboratory for algal studies), the establishment of an algal bank (with an emphasis on regional algae), and the establishment of a plant herbarium (with an emphasis on the regional plant flora) are underway as fundamental and important infrastructures for plant and algal studies. The formulation of national and international standards and the commercial production of various products from the studied plant and algal sources, with the participation and collaboration of related research centers, including the East Azerbaijan Provincial Department of Standards and the Tabriz Food Biotechnology Research Institute, are also other important objectives in these projects. Plants (especially medicinal plants) and algae are used as sources for producing natural compounds required by humans in the pharmaceutical, food, cosmetic-hygienic, biofuel production, and other industries. Today, the use of these valuable resources has attracted the attention of many researchers in the field of biotechnology more than ever. The utilization of medicinal plants such as Stevia rebaudiana (as a natural sweetener) and microalgae such as Spirulina (as a rich source of protein and phycocyanin pigment), Haematococcus pluvialis (as a source of astaxanthin pigment production), Dunaliella salina (as a source of beta-carotene pigment production), and Chlorella vulgaris is being carried out in many research centers and knowledge-based companies related to the field of biotechnology. Iran, due to its high natural potential in the field of medicinal plants and algal resources, also provides a very suitable ground for research and development in this area.
