  • Patent number: 11592438
    Abstract: A system for assaying forces applied by cells includes an optically transparent substrate comprising a soft material having a Young's modulus within the range of about 3 kPa to about 100 kPa. An array of molecular patterns is disposed on a surface of the optically transparent substrate, the molecular patterns include fluorophore-conjugated patterns adherent to cells. The system includes at least one light source configured to excite the fluorophore-conjugated patterns and an imaging device configured to capture fluorescent light emitted from the fluorophore-conjugated patterns. Dimensional changes in the size of the patterns are used to determine contractile forces imparted by cells located on the patterns.

  • Publication number: 20220384081
    Abstract: Embodiments herein are directed to a system and a method of selectively manipulating magnetically-barcoded materials from background magnetic materials. Magnetic barcodes include layers of magnetic anisotropy. These are then manipulated by a magnetic system that can drive spatio-temporal magnetic fields that can “match” a barcode to drive a specific interaction, thereby providing a “lock-key” interaction. This technique is able to selectively manipulate magnetically-barcoded materials, and can have applications across a variety of magnetic systems such as cell separation, drug delivery, valves, and motors.

  • Publication number: 20220255356
    Abstract: A sensor device includes an inner hydrogel layer, a first planar metallic structure adjacent to a first surface of the inner hydrogel layer, and a second planar metallic structure adjacent to a second surface of the inner hydrogel layer opposite to the first surface. A sensor device further includes an encasing layer at least partially enclosing at least one of the inner hydrogel layer, the first planar metallic structure, and the second planar metallic structure. A method for use of the sensor device includes receiving at least one environmental stimulus, modifying a capacitance of a hydrogel in response to the received environmental stimulus, and generating an electrical stimulus response based on the modified capacitance. The method further includes modifying the capacitance of the hydrogel by modifying a resonant frequency of the hydrogel.

  • Patent number: 11248313
    Abstract: This present disclosure provides methods for utilizing such forces in when generating nanofibrillar constructs with engineered morphology from the nano- to macro-scales. Using for example, a biopolymer silk fibroin as a base material, patterns an intermediate hydrogel were generated within a deformable mold. Subsequently, mechanical tension was introduced via either hydrogel contraction or mold deformation, and finally a material is reentrapped in this transformed shape via beta-sheet crystallization and critical point drying. Topdown engineered anchorages, cables, and shapes act in concert to mediate precision changes in nanofiber alignment/orientation and a macroscale form of provided nanofibrillar structure. An ability of this technique to engineer large gradients of nano- and micro-scale order, manipulate mechanical properties (such as plasticity and thermal transport), and the in-situ generation of 2D and 3D, multi-tiered and doped, nanofibrillar constructs was demonstrated.

  • Patent number: 10144911
    Abstract: A system is provided for the quantitative magnetic separation of magnetic objects (e.g., particles or cells). The system uses magnetic ratcheting over arrays of ferromagnetic elements having gradient spacing manifested in various pitch zones that are encountered by the magnetic objects as they traverse the array. The system can be used to separate and concentrate magnetic objects based on iron oxide content. For cells, different phenotypes may be separated based, for example, on surface expression of proteins or molecules that are bound to magnetic particles. The system includes a substrate or chip having the array of ferromagnetic elements with increasing lateral pitch and an externally driven magnet device that generates a cycling magnetic field. Magnetic objects with higher IOC separate and equilibrate along the array at larger pitches. The system can be used for the differential sorting of particles and cells of interest.
