Abstract: System and methods for spectrophotometers are described that can utilize ferrules configured to hold a sample test droplet therebetween via surface tension. Light sources in the systems can shine a light on the test droplet and an output of reflected or refracted light can be measured, which can assist in various testing and analysis procedures. Nanoscale or microscale structures can be incorporated on the ferrules to create hydrophobic or superhydrophobic surfaces. This helps prevent test droplets from wetting the ferrules surfaces and helps prevent polluting or mixing of test materials. The ferrules can therefore achieve certain self-cleaning capabilities and test results are more accurate.

Abstract: A remedial hand wear article is for use by individuals who have suffered nerve damage which diminishes use of the hand. The article comprises (a) a glove for comfortably fitting onto a hand of an individual, (b) an enclosure permanently attached on the glove's top side and superimposed over at least one finger of the glove, and (c) a substantially rigid member positioned within the enclosure and contoured to follow the shape of a top of the individual's hand and to be operably associated with at least one finger of the individual to hold the at least one finger in a desired position and so that full finger flexure at proximal and distal knuckles is retained. The hand wear article is designed to remedy problems caused by different nerve damage in that one to five enclosure elongated sections are permanently attached over glove fingers depending on which finger(s) of the individual is affected by the damaged nerve.

Abstract: A remedial hand wear article is for use by individuals who have suffered nerve damage which diminishes use of the hand. The article comprises (a) a glove for comfortably fitting onto a hand of an individual, (b) an enclosure permanently attached on the glove's top side and superimposed over at least one finger of the glove, and (c) a restraining member positioned within the enclosure so as to be operably associated with a finger of the individual to hold that finger in a desired position. The hand wear article is designed to remedy problems caused by different nerve damage in that one to five enclosure elongated sections are permanently attached over glove fingers depending on which finger(s) of the individual is affected by the damaged nerve. The glove portion of the hand wear article provides comfort to the user while also serving to lessen the noticeability of any hand or finger grotesqueness.
