Abstract: A method for feedback-based supercooling. One or more composition characteristics of an object are identified. A value for the identified composition characteristics are determined. One or more parameters are determined for one or more fields, including electromagmentic, magnetic or electric fields based on the determined values for one or more of the identified composition characteristics. The object is supercooled by applying the fields to the object using the parameters. One or more of the composition characteristics or characteristics of the field are monitored during application of the fields via at least one feedback sensor and one or more of the parameters for the field are adjusted based on the monitored composition characteristics or field characteristics.

Abstract: A feedback system that identifies characteristics of an object and utilizes the characteristics to initiate and adjust a field applied to the object is provided. The system includes an array of array phase elements made of metamaterials that allow precise shaping of the field to be applied to a particular portion of an object based on characteristics of the object, including location and thickness of the object. Sensors are utilized during supercooling to monitor a condition of the object being supercooled. Specifically, characteristics of the object are measured at different points, areas, or volumes on the object and the measurements are used to determine whether supercooling (or another desired result) is being achieved or whether the object is starting to freeze. Based on the measurements, parameters of the field can be adjusted to ensure supercooling of the object without freezing.

Abstract: A feedback-based system and method that identifies characteristics of one or more cells and utilizes the characteristics to initiate and adjust a field applied to the one or more cells to control the cells' functioning and motility is provided. Machine learning can be leveraged to automatically identify characteristics of the one or more cells and adjust the parameters of the field based on the characteristics. Sensors are utilized during the application of the field to monitor characteristics of the one or more cells and parameters of the field. Specifically, characteristics of at least some of the cells are measured at different points, and the measurements are used to determine whether the desired effect has been achieved or whether unintended consequences are taking place. Based on the measurements, parameters of the field can be adjusted to achieve the desired effect on cell functioning, cell motility, or both.

Abstract: A feedback system that identifies characteristics of one or more cells being grown on a metasurface and utilizes the characteristics to initiate and adjust a field applied to the metasurface to control adhesion of the cells to and from the metasurface. The metasurface includes a plurality of structures whose resonances (localized or non-localized) have a wavelength range of 250 nm-3 microns. In one embodiment, the system leverages machine learning to automatically identify characteristics of the one or more cells or the metasurface and adjust the parameters of the field based on the characteristics. Sensors are utilized during the application of the field to monitor characteristics of the one or more cells or the metasurface and parameters of the field. Based on the measurements, parameters of the field can be adjusted to achieve the desired effect on the detachment of the cells.

Abstract: A feedback system that identifies characteristics of a colloid and utilizes the characteristics to initiate and adjust a field applied to the colloid is provided. In one embodiment, the system leverages machine learning to automatically identify a condition of the colloid and adjust the supercooling parameters. Sensors are utilized during supercooling to monitor a condition of the colloid being supercooled. Specifically, characteristics of the colloid are measured at different points, areas, or volumes on the colloid and the measurements are used to determine whether supercooling is being achieved or whether the colloid is starting to freeze or undergoing another undesirable phase change. Based on the measurements, parameters of the field can be adjusted to ensure supercooling of the colloid without freezing or causing another undesirable phase change. When phase change is desired, rate of phase change can be controlled to achieve desired characteristics of the colloid.

Abstract: A particle is provided that includes a first material and a second material, arranged to provide a Fano resonance effect, for example in the visible portion of electromagnetic spectrum. The first and second materials may be substantially clear in the visible portion of the electromagnetic spectrum. The first material may include an inorganic material, such as SiO2, TiO2, HfO2, ZrO2, diamond, or a combination thereof. The second material may include a polymer. The first material has a first refractive index and the second material has a second refractive index, where the first refractive index and second refractive index have a difference of 0.5 or greater, and 1.0 or less. The first material may form a core and the second material may form a shell surrounding the core. Alternatively, the first and second materials may form a Janus particle, an asymmetric dimer, or an aggregate.
