摘要:
The invention relates to a method for preparing monodispersed biodegradable microspheres consisting in a) preparing an emulsion containing at least one polymeric phase and at least one aqueous phase at a viscosity ratio between the dispersed polymeric phase and the aqueous phase ranging from 0.12 to 10, b) exposing the thus obtained emulsion to a controlled laminar shear strength, c) removing a solvent from the polymeric phase and in d) isolating the thus obtained microspheres. The use of the prepared microspheres is also disclosed.

摘要:
This method includes the provision of a first fluid (36) including the first phase and a first precursor polymer of the coacervate contained in the first phase, and the formation of drops of the first fluid (36) in a second fluid (40) intended to form the second phase (16). It includes the steps of introducing a second precursor polymer of the coacervate into the second fluid (40) and, during the formation of each drop (12), or once each drop (12) has been formed, for generating the coacervate layer by interaction between the first precursor polymer and the second precursor polymer at the interface between the first phase (14) and the second phase (16).

摘要:
The invention describes a method for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, comprising the steps of: a) compartmentalising the compounds into microcapsules together with the target, such that only a subset of the repertoire is represented in multiple copies in any one microcapsule; and b) identifying the compound which binds to or modulates the activity of the target; wherein at least one step is performed under microfluidic control. The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.
