Laser photofabrication of cell-containing hydrogel constructs.
The two-photon polymerization (2PP) of photosensitive gelatin in the presence of living cells is reported. The 2PP technique is based on the localized cross-linking of photopolymers induced by femtosecond laser pulses. The availability of water-soluble photoinitiators (PI) suitable for 2PP is crucial for applying this method to cell-containing materials. Novel PIs developed by our group allow 2...
متن کاملLaser-targeted photofabrication of gold nanoparticles inside cells.
Nanoparticle manipulation is of increasing interest, since they can report single molecule-level measurements of the cellular environment. Until now, however, intracellular nanoparticle locations have been essentially uncontrollable. Here we show that by infusing a gold ion solution, focused laser light-induced photoreduction allows in situ fabrication of gold nanoparticles at precise locations...
متن کاملDynamics of cytochrome bf complex of photosynthesis apparatus
Photosynthesis is a process under which, the radiative energy is converted into the chemical one. Compared to the man-made devices, the photosynthesis apparatus is much more efficient. This high efficiency comes from its elaborate structure, very fast transition rates and a complex electron and proton transfer chain among the subunits of the apparatus. Its main subunits (Photosystem I (PSI), bf...
متن کاملDosimetry of Occupational Radiation around Panoramic X-ray Apparatus
Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...
متن کاملIdentification and Assessment of Human Error during the Process of Operating Various Types of Fire Apparatus
Background and Aim: Firefighting is a difficult and dangerous job. This job requires decision-making and speed of action in critical situations. Such conditions increase the probability of human error in the firefighting activities. Setting up fire apparatus as the first step of emergency response is associated with high criticality. The purpose of this study is identification and assessment th...
