The present application is directed to a system and device for attraction of pests. This system comprises CO.sub.2-releasing microorganisms, and also nutrients specific to these microorganisms, and this system, or the device, comprises one or more biodegradable biopolymers and allows CO.sub.2, and optionally other attractants, to be released over a period of more than 20 days. Furthermore, the present application provides for the use of such a system or such a device for the attraction of pests, more particularly of maize or potato pests, such as larvae of the Western corn rootworm or wire worm. The present application is also directed, lastly, to methods for attracting pests, more particularly pests of maize or potatoes, such as the larvae of the Western corn rootworm, or for wire worms, with the systems or devices of the invention being positioned in the immediate vicinity of the plants, but preferably not directly on the plants.

The present invention concerns a suspension of a polymer comprising, in addition to said polymer, a) a liquid medium; b) a monovalent cation salt; c) an alginate.

In a method of integrating an active pharmaceutical ingredient (API) with a thermoplastic polymer, the thermoplastic polymer and API are into a first feed port of a multi-screw extruder or the thermoplastic polymer is fed into the first feed port of a multi-screw extruder, the thermoplastic polymer is conveyed along the heated multi-screw extruder while heating the thermoplastic polymer to a melt temperature of 160° C.-280° C. prior to the thermoplastic polymer being conveyed past a second feed port and the API is fed into the second feeding port in the heated screw extruder to mix with the melted thermoplastic polymer to generate a compounded mixture containing 85-100% of the starting API content. The compounded mixture is extruded from an outlet of the heated screw extruder and cooled via a cooling device such that the compounded mixture contains 85-100% of the starting API content.

Disclosed herein is a nano-coating platform that is designed to ‘capture’ and ‘kill’ (i.e. inactivate) virus species to prevent surface to surface contamination/transmission and thereby the spread of novel viruses. The platform is comprised of alternating layers of charged polymers (producing a multi-layer coating). The cationic layer may be grafted with oligomeric species, chosen to bind strongly to unique/specific virus surface features, thereby mediating capture of the virus (with the choice of oligomeric species allowing generalization to a given virus). Natural light (excitation) to UV (local emission) up-converting nanoparticles are seeded into the anionic layer and mediate the inactivation (‘killing’) of the bound virus species.
