Method of isolation and purification of xanthophylls from diatom culture Xanthophylls, with their antioxidant, anticancer, anti-inflammatory and neuroprotective properties, found important applications in food and nutrition, cosmetic and environmental industries, as well as pharmacy and medicine. Diadinoxanthin (Ddx) and diatoxanthin (Dtx) are two pigments that belong to xanthophylls family. The availability of Ddx and Dtx on the market is low and up to date limited as they are sold exclusively in small quantities at extremely high prices to be used as HPLC calibration standards. The solution of the above mentioned problems is the 5-step method for the isolation and purification of Ddx and Dtx developed at the Jagiellonian University..

Method for dioxin and furan extraction, cleanup and analysis Method to measure a very low concentration of dioxins (values close to picograms or femtograms). The technique also permits the quantitative analysis of almost all the congeners of dioxins and furans (more than 130 different compounds), not only the main 17 toxic compounds. The technique could be applied to different fields: gaseous emissions from the combustion, characterization of hazardous and toxic wastes, determination in food and feed, determination in sewage sludges and other organic fertilizers, determination in other matrices such as tissues and blood, air, emission due to the traffic, paper, ink, hygienic materials, tobacco smoke, chimney soot, dust… Innovative aspects: − The know-how involves the ability to measure a very low concentration of dioxins (values close to picograms or femtograms). It does not depend on the precise equipment but the expertise in preparing properly the samples by means of a very sensitive and specific analytical method. − The technique also permits the quantitative analysis of almost all the congeners of dioxins and furans (more than 130 different compounds), not only the main 17 toxic compounds. − Nowadays, this methodology (standard one) is the only one available method to carry out reliable dioxin analyses.

PSA purification and concentration from urine samples for non-invasive early stage diagnosis of prostate cancer New method for the pretreatment of human urine sam-ples, comprising the simultaneous extraction, concentration and purification of the prostate-specific antigen (PSA), a prostate cancer biomarker. In this technology, aqueous biphasic systems composed of ionic liquids and salts are used. These systems allow the selective extraction of PSA and to obtain high con-centration/enrichment factors, enabling the quantification of PSA using less sophisticated, cheaper and more affordable equipment.
