A freshness indicator comprises a support structure that is substantially impermeable to fluids. A test device is engaged with the support structure and includes a pathogen detection composition. The pathogen detection composition provides a prescribed visual indication when in the presence of a prescribed type of pathogens and/or a by-product thereof. A flow limiting structure extends over the test device and has an entire perimeter edge portion thereof attached to the support structure in a manner whereby the flow limiting structure and the support structure jointly form a fluid resistant interface around a space in which the test device resides. The flow limiting structure substantially allows a portion of the prescribed type of pathogen and/or a portion of the by-product thereof to enter the space in which the test device resides and substantially inhibits any portion of the pathogen detection composition from escaping from the space in which the test device resides.
Biodegradable polyesters are made by synthesizing copolymers derived from biodegradable hydroxyacid monomers as well as from hydroxyacid monomers containing a functional group such as an azide group, a halogen group, a thioacetate group, and the like. Preferably, the functionalized biodegradable polyester copolymers are derived from a functionalized hydroxyacid such as a homolog of lactic acid and/or glycolic acid with the copolyester thus containing functional groups on the backbone thereof. These biodegradable polyesters can be utilized wherever biodegradable polyesters are currently used, and also serve as a polymer to which various medical and drug delivery systems can be attached.
