  • Patent number: 11155576
    Abstract: Disclosed are peptides that contain up to about 35 amino acids, including a plurality of aromatic amino acid residues and either (i) an amino acid residue that is phosphorylated or sulfated, or (ii) an amino acid comprising an ester-moiety linked via peptide bond, or both (i) and (ii), wherein the peptide is capable of self-assembly to form nanofibrils in the presence of an enzyme that hydrolyzes the phosphate group, the sulfate group, or the ester-moiety. These peptides are enzymatically responsive hydrogelators, and they can be used to form pericellular hydrogels/nanofibrils upon exposure to target cells that secrete or express a surface bound ectoenzyme having hydrolase activity suitable to induce peptide gelation. These materials, and compositions containing the same, can be used for in vitro and in vivo cellular imaging, treating cancerous conditions, collecting a secretome from a cell upon which the pericellular hydrogels/nanofibrils form, and screening the collected secretome.

  • Patent number: 11152927
    Abstract: A low distortion triangular wave generator circuit generates a triangular wave signal by performing integration on an integration capacitor via a charging current and a discharging current during a charging period and a discharging period within a switching period of an external clock signal. A time length of the charging period is identical to a time length of the discharging period. A common mode related signal related to a common mode characteristic of the triangular wave signal is generated. An adjusting signal is generated according to a difference between the common mode related signal and a predetermined DC (direct current) level. The adjusting signal adjusts at least one of the charging current and the discharging current via feedback mechanism such that the triangular wave signal is a symmetrical triangular wave, and an average voltage of the triangular wave signal is equal to a target DC level.

  • Patent number: 10308682
    Abstract: Disclosed herein are fibrillar molecular aggregates, which are morphologically and phenotypically similar to oligomers of aberrant proteins. The molecular aggregates, formed by self-assembly of small hydrophobic molecules, prevent the growth of microtubules. This unprecedented mechanism of “self-assembly to interfere with self-organization” allows inhibition of the growth of cancer cells.

  • Patent number: 9899915
    Abstract: This invention proposes using a feed forward quasi universal converter for energy harvesters, and uses it to power IoTs (Internet of things). A typical DC to DC converter uses voltage feedback control or current feedback control. It is not easy for the input impedance to closely match the output impedance of the power source. In the meantime, it also meets its output voltage and power targets. The Feed forward Quasi Universal Converter proposed in this invention controls the input impedance and the output voltage/power within a range that meets the design targets. It is also achieved with a simple electronic adjustment when the source impedance changes or the output requirements change. It has the potential to shorten the IoTs system industry's product development cycle, reduce installation and maintenance costs and facilitate the adoption of hybrid energy sources.

  • Patent number: 9408921
    Abstract: Disclosed is a general methodology to create nanofibers of therapeutic molecules that have a dual role, as both the delivery vehicle and the drug itself. It is shown that with proper molecular design, the integration of enzymatic reaction and self-assembly provides a powerful method to create molecular hydrogels of clinically-used therapeutics without compromising their bioactivities. In addition, the results disclosed herein demonstrate enzyme-instructed self-assembly as a facile strategy for generating the supramolecular hydrogels of molecules that inherently have poor solubility in water. For example, by covalently connecting paclitaxel with a motif that is prone to self-assemble, a hydrogel of paclitaxel can be formed without compromising the activity of the paclitaxel.
