SINGLE-USE CONTACT TIP FOR TONOMETER
A contact tip for a contact tonometer has a body including a contact surface, and a coating applied to the contact surface. The coating includes a light-activated material and a biocompatible water soluble adhesive for adhering the coating to the contact surface. The water soluble adhesive dissolves upon contact with the corneal tear film during a tonometric measurement, thereby releasing the light-activated material into the tear film. The present disclosure further provides a single-use tonometer contact tip product which includes a sterilized contact tip having the mentioned contact surface coating, and an opaque package containing the sterilized contact tip.

Biopolymer-based seed coatings compositions and methods for use
A seed or seedling is coated with a cross-linked biopolymer and, optionally, a second binder selected from underivatized guar, cationic hydroxypropyl guar, polyacrylamide, poly(methacrylic acid), poly(acrylic acid), polyacrylate, poly(ethylene glycol), polyethyleneoxide, polyamide, hydroxypropyl guar, carboxymethyl guar, carboxymethylhydroxypropyl guar, underivatized starch, cationic starch, corn starch, wheat starch, rice starch, potato starch, tapioca, waxy maize, sorghum, waxy sarghum, sago, dextrin, chitin, chitosan, xanthan gum, carageenan gum, gum karaya, gum arabic, pectin, cellulose, hydroxycellulose, hydroxyalkyl cellulose, hydroxyethyl cellulose, carboxymethylhydroxyethyl cellulose, or hydroxypropyl cellulose. The seed coating composition is characterized by a dust value, as measured using a Heubach dustmeter device, which is lower by at least 30% as compared to an analogous composition that does not contain the crosslinked biopolymer.

PRECURSORS FOR FORMING HETEROPHASIC ODOR-ABSORBING AND ANTI-FOULING POLYMERIC COATINGS
An aqueous or water-borne precursor liquid for forming an odor-absorbing and anti-fouling heterophasic thermoset polymeric coating is provided. The precursor includes a fluorine-containing polyol precursor having a functionality >about 2 that forms a branched fluorine-containing polymer component defining a first phase in the anti-fouling heterophasic thermoset polymeric coating. The precursor also includes a first precursor that forms a first component including a cyclodextrin present as second phase. The first phase can be a continuous phase and the second phase can be a first discrete phase, or the second phase can be the continuous phase and the first phase can be the first discrete phase. A crosslinking agent, water, and optional acid or base are also present. An emulsifier may also be included. Methods of making an odor-absorbing and anti-fouling heterophasic thermoset polymeric coatings with such precursors are also provided.

Coating of a vascular endoprosthesis
The invention relates to a method for coating a vascular endoprosthesis, wherein the outside of the vascular endoprosthesis is wetted at least partially with a first solution of an active substance, the vascular endoprosthesis is moved in a rotational movement about the longitudinal axis of the vascular endoprosthesis, and a radially acting mechanical force is applied to the outside of the vascular endoprosthesis. The rotational movement has the effect that the solution is carried outward by the centrifugal force, such that no active substance deposits in the interior of the vascular endoprosthesis. The application of a mechanical force to the outside of the vascular endoprosthesis then has the effect of creating crystallization nuclei, such that the active substance can crystallize out.
