    Abstract: Microspheres for controlled release of a bioactive agent are disclosed, and in particular, blend, cross-linkable poly(propylene fumarate) for immobilization and controlled drug delivery. The microsphere includes poly(propylene fumarate), a polymeric material other than poly(propylene fumarate) (e.g., poly(lactic-co-glycolic acid)), and a bioactive agent. The bioactive agent is selected depending on the physiological effect desired. For example, in bone regeneration applications, the bioactive agent may be selected from osteoinductive agents, peptides, growth hormones, osteoconductive agents, cytokines and mixtures thereof. The bioactive agent is dispersed in the microsphere, the microsphere has a diameter in the range of 1 to 300 micrometers, the poly(propylene fumarate) and poly(lactic-co-glycolic acid) are distributed in the microsphere, and the microsphere releases the bioactive agent in a sustained manner after an initial burst release. The microspheres may be covalently attached to a poly(propylene fumarate) scaffold for tissue regeneration applications in which the bioactive agent is released from the scaffold.

    Abstract: A thin-film transistor (TFT) includes a gate electrode, an oxide semiconductor pattern, a source electrode, a drain electrode and an etch stopper. The gate electrode is formed on a substrate. The oxide semiconductor pattern is disposed in an area overlapping with the gate electrode. The source electrode is partially disposed on the oxide semiconductor pattern. The drain electrode is spaced apart from the source electrode, faces the source electrode, and is partially disposed on the oxide semiconductor pattern. The etch stopper has first and second end portions. The first end portion is disposed between the oxide semiconductor pattern and the source electrode, and the second end portion is disposed between the oxide semiconductor pattern and the drain electrode. A sum of first and second overlapping length is between about 30% and about 99% of a total length of the etch stopper.
