The present invention relates to an average-density-adjustable structure and more specifically provides a structure the average density of which is adjusted by changing the material of the structure and the size of a void formed therein and which can thereby float on the surface of or in a liquid and can easily bond with or change a material present in a gas or liquid by being equipped with a first material, which is one among an organic catalyst, an inorganic catalyst, a microorganism, and a biomolecule.

Improved methods for drying for bio-compatible solid phase microextraction (BioSPME) coatings yielding coatings with highly consistent extraction efficiency and biocompatibility. The methods, adapted to flow-through drying systems involve determining relative humidity in and around the drying system, determining a drying temperature range based on the relative humidity, and maintaining the drying temperature within the determined range while drying the coating.

An improved device for solid phase microextraction, the device including a plastic substrate, a pre-coating layer on the plastic substrate, and an SPME coating on the precoating layer. SPME coatings are typically incompatible with plastic substrates due to differences between the surface energies of the substrate and the coating, leading to uneven coating and poor adhesion. The addition of the precoating layer provides increased evenness and stronger adhesion of the SPME coating to the plastic substrate. Also provided are method of coating an SPME coating on a plastic substrate, the method including the step of precoating the plastic substrate to provide a precoated substrate and then coating the precoated substrate with an SPME coating, wherein precoating provides improved coating evenness and adhesion of the SPME coating to the plastic substrate.
