A method of assaying the interaction of a molecule and a lipid bilayer is described. The method employs a microfluidic device comprising a substrate having at least one concave microcavity with a metallic surface defining an aperture and a liquid disposed within the microcavity, a lipid bilayer suspended across the aperture, and a microfluidic channel containing a liquid disposed on top of the substrate in fluid communication with the lipid bilayer. The method comprises the steps of passing a liquid containing a test molecule across the microfluidic channel, and monitoring lipid bilayer molecule interactions by plasmonically enhanced Raman or fluorescence spectroscopy configured for plasmonic enhancement of a detection signal evolving from the test molecule or lipid bilayer. Also described in a microfluidic device configured to perform the method of the invention.

The invention relaters to a microparticle for bioanalytical investigations and a method for its production. The microparticle is suitable for being transported through a flow cell of a flow cytometer in a fluid stream. The microparticle has a solid particle core and at least one nucleic acid sense biomolecule that is binding-specific for an antisense biomolecule. A layer composed of a water-soluble conjugate is arranged on the particle core, which layer includes at least one linear polymer and/or copolymer, which has at least one first group, by means of which the polymer and/or copolymer can be cross-linked by means of irradiation with an optical radiation having a discrete wavelength, has at least one second group, to which the at least one nucleic acid sense biomolecule is conjugated, and has at least one third group that is bound to the surface of the particle core by way of a functional linker group, wherein the linker group is not capable of binding to the at least one nucleic acid sense biomolecule.

A method for controlled production of an array of planar microparticles with the multiplexing of molecules on the surface thereof, intended to function as molecular sensors and/or actuators and a matrix (array) of microparticles, the surface thereof being printed with all of the molecular components required to provide the surface with functionality. Different molecular elements are multiplexed on the surface of each particle while they are supported on a substrate by means of a structural foot engraved below the particle. These microparticles can be released mechanically from the support on which they are produced using a controlled mechanical rupture method which is not chemically aggressive and therefore does not affect the molecules previously printed on the surface. The array and the particles contained therein offer great versatility in both chemical and/or biological applications.
