A portable apparatus for detecting the presence of methylxanthine chemical species such as caffeine or theophylline in a solution such as a beverage comprises a first portion comprising an effective concentration of at least one phosphodiesterase enzyme, a second portion comprising an effective concentration of cyclic AMP, and means for indicating the inhibition of the degradation of cyclic AMP by phosphodiesterase due to the presence of at least one methylxanthine compound. A method for determining the presence of methylxanthine chemical species in a solution such as a beverage comprises contacting at least one test portion of the solution with effective concentrations of at least one phosphodiesterase enzyme and cyclic AMP, and thereafter contacting the test portion with means for indicating the inhibition of the degradation of cyclic AMP by phosphodiesterase due to the presence of at least one methylxanthine compound. The apparatus and method are advantageous in that they provide a simple and effective means of determining whether methylxanthine chemical species such as caffeine or theophylline are present in solutions such as coffee, tea and other beverages.

A method for determining the presence of at least one methylxanthine chemical species in a beverage comprises contacting at least one test portion of the beverage with effective concentrations of at least one phosphodiesterase enzyme and cyclic AMP, and further contacting the test portion with means for indicating the inhibition of the degradation of the cyclic AMP by the phosphodiesterase due to the presence of the methylxanthine species. The apparatus and method are advantageous in that they provide a simple and effective means of determining whether methylxanthine chemical species such as caffeine or theophylline are present in coffee, tea and other beverages.

Systems and methods for autonomous intravenous needle insertion are disclosed herein. In an embodiment, a system for autonomous intravenous insertion include a robot arm, one or more sensors pivotally attached to the robot arm for gathering information about potential insertion sites in a subject arm, a medical device pivotally attached to the robot arm, and a controller in communication with the sensors and the robot arm, wherein the controller receives the information from the sensors about potential insertion sites, and the controller selects a target insertion site and directs the robot arm to insert the medical device into the target insertion site.
