Abstract
Intracellular transport is affected by the filament network in the densely packed cytoplasm. Biophysical studies focusing on intracellular transport based on microtubule-kinesin system frequently use in vitro motility assays, which are performed either on individual microtubules or on random (or simple) microtubule networks. Assembling intricate networks with high flexibility requires the manipulation of 25 nm diameter microtubules individually, which can be achieved through the use of pick-and-place assembly. Although widely used to assemble tiny objects, pick-and-place is not a common practice for the manipulation of biological materials. Using the high-level handling capabilities of microelectromechanical systems (MEMS) technology, tweezers are designed and fabricated to pick and place single microtubule filaments. Repeated picking and placing cycles provide a multilayered and multidirectional microtubule network even for different surface topographies. On-demand assembly of microtubules forms crossings at desired angles for biophysical studies as well as complex networks that can be used as nanotransport systems.

Abstract
The concept of a reconstructed microtubule kinesin-based transport system was originally introduced for studies of underlying biophysical mechanisms of intracellular transport and its potential applications in bioengineering at micro- and nanoscale levels. However, several technically challenging shortcomings prohibit its use in practical applications. One of them is the propensity of microtubules to bind various protein molecules creating "roadblocks" for kinesin molecule movement and subsequently preventing efficient delivery of the molecular cargo. The interruption in kinesin movement strictly depends on the specific type of "roadblock", i.e. the microtubule associated protein (MAP). Therefore, we propose to use the "roadblock" effect as a molecular sensor that may be used for functional characterization of particular MAPs with respect to their role in MT-based transport and associated pathologies, such as neurodegeneration. Here, we applied a kinesin-based assay using a suspended MT design (sMT assay) to functionally characterize known MAP tau protein isoforms and common mutations found in familial frontotemporal dementia (FTD). The proposed sMT assay is compatible with an on-chip format and may be used for the routine characterization of MT associated molecules applicable to diagnostics and translational research.
