Abstract: In one aspect, a sample collection device for collecting a biological sample is disclosed, which comprises a sample-receiving cup having a body that extends from a proximal opening to a distal opening, where the proximal opening is configured for receiving a biological sample. The sample collection device further includes a sensor comprising at least one sensing unit, where the sensor is sealingly connected to the distal opening of the sample-receiving cup such that the sensing unit is exposed to the distal opening. A reservoir for storing one or more sample-processing reagents is provided in the fluid-receiving cup such that the sensing unit is in fluid contact with the reagent(s) stored in the reservoir. A frangible membrane separates the reservoir from the proximal opening.

Abstract: A papermaking fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter in the papermaking system. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device in the dryer section to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the dryer section or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.
