    摘要: Provided are proteins/peptides. The proteins or peptides comprise a sequence designed by the methods described herein. The proteins and peptides may have one or more trifluoroleucine (LTF, which may be referred to as TFL or LTF throughout) residues. The proteins may have or contain the following sequence:

The proteins and peptides may have desirable self-assembling properties such that they form supramolecular structures (e.g., fibers or fibrils). The supramolecular structures may further gelate water such that a hydrogel is formed. The fibers and/or gels may be used to deliver drugs and/or as theranostic agents.

    摘要: According to one embodiment, an inspection device includes a transmitter configured to transmit a first ultrasonic wave, a receiver on which the first ultrasonic wave is incident, and a receiving-side waveguide located between the receiver and an inspection position. The receiver is configured to output a signal corresponding to the incident first ultrasonic wave. The inspection position is between the transmitter and the receiver. The first ultrasonic wave passes through the receiving-side waveguide. An inspection object passes through the inspection position along a second direction crossing a first direction. The first direction is from the transmitter toward the receiver. The receiving-side waveguide includes at least one of a first structure or a second structure. In the first structure, the receiving-side waveguide includes a tubular member and an inner member. The inner member is located inside the tubular member. In the second structure, the receiving-side waveguide includes a tubular member.
