Method for sample analysis in an automatic analyser
A foil and its use in a method for analyzing a sample in an automatic analyzer, comprising the steps of providing foil comprising at least one immobilized reagent; forming the foil to a receptacle; adding the sample to the receptacle; and analyzing a reaction between sample and immobilized reagent.
1 . A method for analyzing a sample in an automatic analyzer, comprising the steps of:
a) providing foil comprising at least one immobilized reagent
b) forming the foil to a receptacle;
c) adding the sample to the receptacle; and
d) analyzing a reaction between sample and immobilized reagent.
2 . The method according to claim 1 , wherein a step of immobilizing the reagent onto the foil is performed into the same device that will subsequently perform steps a) to d) of claim 1 .
3 . The method according to claim 1 , wherein the foil is formed to a pipette tip, tube, cavity, bottle, well or multi-well.
4 . The method according to claim 1 , wherein forming the foil comprises a thermal deformation or a winding process.
5 . The method according to claim 1 , wherein immobilization of the reagent is performed by printing the reagent onto the foil.
6 . The method according to claim 1 , wherein analyzing a reaction comprises detecting an immune, chemical or enzymatic reaction.
7 . The method according to claim 6 , wherein detecting a chemical or enzymatic reaction comprises initiating an immune, fluorescence or a luminescence reaction.
8 . The method according to claim 1 , wherein adding a sample is a result of using a foil formed to a pipette tip for transfer of the sample.
9 . The method according to claim 1 , wherein the sample is added to a foil formed to a receptacle for carrying out the analyzing step.
10 . The method according to claim 1 , further comprising the step of printing at least one hydrophilic and at least one hydrophobic area onto the foil, before forming the foil.
11 . The method according to claim 10 , comprising the step of printing the hydrophobic area around the hydrophilic
12 . The method according to claim 1 , comprising the step of providing a foil at the sample area that is located at the tip of the receptacle and a reaction area comprising the reagent, wherein the sample area and the reaction area are connected by a channel and the reaction area is connected by a further channel to a waste area so that the sample can flow from the sample area to the reaction area further to the waste area.
13 . A foil comprising at least one immobilized reagent, wherein the foil is made of a material allowing to form it into a receptacle.
14 . The foil of claim 13 , comprising at least one hydrophilic area and at least one hydrophobic area, wherein the at least one hydrophobic area surrounds the at least one hydrophilic area.
15 . The foil of claim 13 , wherein multiple hydrophilic areas are connected by channel.
16 . The foil of claim 13 , wherein a first hydrophilic area is intended for taking up a sample and a second hydrophilic area comprises the at least one immobilized reagent.
17 . The foil of claim 16 , wherein a third hydrophilic area is a waste area for taking up residues from a chemical or enzymatic reaction within the second hydrophilic area.
18 . The foil of claim 13 , wherein the foil is formed to a pipette tip, tube, cavity, bottle, well or multi-well.
19 . A method of using a foil comprising at least one immobilized reagent, wherein the foil is made of a material allowing to form it into a receptacle comprising the step of providing the foil in an automated analyzer system for analyzing samples.
