Public Contracts Schedule

Public procurement – investment to the infrastructure and equipment

• the list of equipment and devices had been already planned in the project application (see table below)
• in case of positive difference between the estimated price and contracted price, the financial resources could be used further within the project, however a non-planned equipment must be consulted ex-ante with the OP VVV office (it is necessary to check the eligibility of such new investment and submit a request to the Ministry of education)
• it is obligatory to record a device usage book   for each device financed from the OP VVV project

Purpose of the purchased equipment:
NTA is a key method for analysis of size distribution of nanoparticles in solution, distribution of their optical properties and estimation of their concentration. For experimental work with sensoric nanosystems proposed for biomedicinal applications in WP5, it is highly requisite to estimate a number concentration of particles in diluted solutions of small volumes (after a number of purification steps, the concentrations of these solutions are not known). In comparison with methods available at IOCB (quasielastic light scattering), this method provides more accurate and more reproducible results. Most importantly, NTA enables distinguishing fluorescent and non-fluorescent particles in the solution. This will be necessary for analysis of number-weighted distribution of fluorescence in systems of anisotropically irradiated nanoparticles. The method will be further used for analysis of dynamic aggregation status of colloidal solutions of nanosensors developed in WP5. The method will be utilized also in WP2 for analysis of detonation nanodiamond solutions and investigation of their dynamic association behavior which depends on the used purification approach and degree of surface modification.
