  • Patent number: 9873939
    Abstract: A microfluidic device for use with a microfluidic delivery system, such as an organic vapor jet printing device, includes a glass layer that is directly bonded to a microfabricated die and a metal plate via a double anodic bond. The double anodic bond is formed by forming a first anodic bond at an interface of the microfabricated die and the glass layer, and forming a second anodic bond at an interface of the metal plate and the glass layer, where the second anodic bond is formed using a voltage that is lower than the voltage used to form the first anodic bond. The second anodic bond is formed with the polarity of the voltage reversed with respect to the glass layer and the formation of the first anodic bond. The metal plate includes attachment features that allow removal of the microfluidic device from a fixture.

  • Patent number: 9863863
    Abstract: The invention relates to a sensor apparatus (100) and a method for detecting clusters with magnetic particles in a sample. The sample is provided in at least one sample chamber (114) of a substantially planar cartridge (110) that is exposed to a modulated magnetic field (Bxz, Byz) generated by a magnetic field generator (190). The sample chamber (114) is illuminated with excitation light (L0), and the resulting output light (Ls) is detected by a light detector (180). The magnetic field (Bxz, Byz) may particularly rotate, inducing a corresponding rotation of clusters which in turn induces a variation of the detection signal (S). According to a preferred embodiment, excitation light (L0) is focused onto blocking spots (173) behind the sample chamber (114), thus shielding the light detector (180) from direct illumination.
