Abstract: Chlorotoxin derivatives containing amino acid sequence X0X1CMPCXS1XS2XS3DHXS4XS5ARRCX2X3CCGGYGX4CFGYQC LCX5X6X7X8 wherein (i) the N-terminal X0X1 cluster is AM, 0M, or 00; (ii) the solubility XS1XS2XS3XS4XS5 cluster is FTTQT, FTTES, SSSQT, SSSES, FSSQT, FSSES, or FSSQS; (iii) the internal X2X3X4 cluster is DKR, RDK, KDR, IKY, HKW, DRK, LKQ, KKK; and (iv) the C-terminal X5X6X7X8 cluster is N000, R000, NR00, NRG0, NRGY, NRRR, or RRRR; 0 denotes a position where no amino acid is present; the chlorotoxin derivative has a relative human MMP-2 binding that is at least 1.62 times higher than the wild-type chlorotoxin of SEQ ID NO: 1.

Abstract: A sensor cleaning apparatus, for cleaning a sensor field of a sensor, in particular a LiDAR sensor, of a vehicle, includes at least one wiper drive housing, which houses at least a majority of at least one wiper drive unit. At least one wiper is arranged at least partially outside of the wiper drive housing and is configured to clean the sensor field by way of a wiping motion. At least one wiper receiving element is provided for transferring a drive movement from the wiper drive unit to the wiper. The sensor cleaning apparatus further includes a sealing unit configured for an at least water-tight seal of the wiper drive housing and includes at least one movable passage opening for the wiper receiving element and/or for the wiper.
