Abstract: A method of producing microparticles having a median diameter up to 100 ?m and the microparticles so produced are described. The method includes the steps of providing a solvent having a bioactive dispersed or dissolved therein and a vehicle dissolved therein, carrying out an emulsification in a non-solvent phase to produce an emulsion containing the bioactive and the vehicle in a solvent phase, and evaporating the solvent to leave the microparticles, wherein a mixture of at least two surfactants is employed to stabilize the emulsion and wherein the mixture has a hydrophilic-lipophilic balance (HLB) of up to 8.

Abstract: An apparatus for detecting fluorescently-labeled molecules moving in an electrophoretic separation medium. The apparatus utilizes a scanning detection system in which multiple fluorophores are efficiently and simultaneously detected using dichroic mirrors to allow simultaneous detection of fluorescently-labeled molecules in ultrathin gels labeled with several fluorophores and to permit operation at speeds ten times faster than prior art gel separations. The apparatus also utilizes a detection system where lightweight collection optics are in motion while detection optics are fixed in a remote location, thereby allowing exceptionally high-speed scanning.
