摘要： An optical device, such as a microscope, is disclosed that can be assembled from flat materials. The optical device can be assembled via a series of folds of a flat material. The optical microscope can include a stage for supporting a sample, an optic stage, and a light source. The optic stage can include one or more lenses. The optical microscope can be capable of obtaining simultaneous images from different forms of microscopy. The optical microscope may have bright field and filter field viewing capabilities wherein a user shifts from bright field to filter field by lateral movement of the stage containing a lens and a light source that cooperate to provide either the bright field or the filter field.

摘要： A microfluidic centrifuge is provided that includes a microfluidic disc having a pair of through holes that include a first through hole and a second through hole, where the pair of through holes are disposed symmetric and proximal to a central axis of the microfluidics disc, where the microfluidics disc includes a sealable input port and a sealable output port, where the sealable input port and the sealable output port are connected by a microfluidics channel, and a pair of tethers disposed through the pair of through holes that are disposed to twist about each other for unwinding where the tether unwinding is disposed to interact with the through holes, where the microfluidics disc rotates about the central axis.

摘要： A permanently sealed vacuum tube is used to provide the electrons for an electron microscope. This advantageously allows use of low vacuum at the sample, which greatly simplifies the overall design of the system. There are two main variations. In the first variation, imaging is provided by mechanically scanning the sample. In the second variation, imaging is provided by point projection. In both cases, the electron beam is fixed and does not need to be scanned during operation of the microscope. This also greatly simplifies the overall system.
