Description

KIT Y DISPOSITIVO CILINDRICO PARA LA DETECCIÓN DE UN AGENTE INFECCIOSO. KIT AND CYLINDRICAL DEVICE FOR THE DETECTION OF AN INFECTIOUS AGENT.
CAMPO DE LA INVENCIÓN FIELD OF THE INVENTION
La presente invención está relacionada con la detección de un agente infeccioso a partir de sondas con fibras o papel, y más particularmente está relacionada con un kit y dispositivo cilindrico para la detección de un agente infeccioso. The present invention is related to the detection of an infectious agent from probes with fibers or paper, and more particularly it relates to a kit and cylindrical device for the detection of an infectious agent.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Se han diseñado diferentes clases de ensayos biológicos para la detección de un agente infeccioso a base de papel o fibras, incluidas las varillas de medición, los ensayos de flujo lateral (LFA), los dispositivos analíticos basados en papel (pPAD) y la placa de micropocillos. Dichas plataformas poseen varios beneficios como lo es la rapidez y costos, así como que son ligeras y se necesita poca cantidad de volumen de muestra. Sin embargo, poseen limitaciones como sensibilidad de detección insuficiente, inestabilidad del material (papel o fibra), necesidad de tratamiento en la superficie debido a la naturaleza inerte del papel o fibra y poco tiempo de vida útil después de la activación de la superficie. Different classes of biological assays have been designed for the detection of a paper- or fiber-based infectious agent, including dipsticks, lateral flow assays (LFA), paper-based analytical devices (pPADs), and plate. microwells. These platforms have several benefits such as speed and costs, as well as being light and requiring a small amount of sample volume. However, they have limitations such as insufficient detection sensitivity, instability of the material (paper or fiber), the need for surface treatment due to the inert nature of the paper or fiber, and a short shelf life after surface activation.
Además, la mayoría de los ensayos basados en papel utilizan nitrocelulosa (NC) disponible en el mercado. No obstante, no existe un gran control sobre las propiedades de dicho papel, ya que la calidad del papel puede variar de un fabricante a otro y es conocido que la nitrocelulosa tiene un WCA de 21° a 67°, este nivel de hidrofilia puede inducir una mayor probabilidad de una señal de falso positivo. Por esa razón, las plataformas analíticas en papel generalmente sufren de sensibilidad insuficiente. Por lo tanto, es necesario desarrollar un papel con una morfología de superficie adaptada, propiedades de superficie y humectabilidad ajustada para fines específicos. In addition, most paper-based assays use commercially available nitrocellulose (NC). However, there is no great control over the properties of said paper, since the quality of the paper can vary from one manufacturer to another and it is known that nitrocellulose has a WCA of 21 ° to 67 °, this level of hydrophilicity can induce a higher probability of a false positive signal. For that reason, paper analytical platforms generally suffer from insufficient sensitivity. Therefore, it is necessary to develop a paper with an adapted surface morphology, surface properties and adjusted wettability for specific purposes.
Por ejemplo, el documento W02007/106050 describe una prueba ELISA para detectar anticuerpos específicos de miembros de los flavivirus a partir de muestras biológicas, y se basa en una competencia por la unión del epítopo en la proteína de la envoltura del antígeno de flavivirus capturado usando IgA anti-flavivirus en presencia de suero positivo de flavivirus. Por su parte, el documento CN205679623U describe una fibra de nitrocelulosa cubierta de oro coloidal y kit de detección del antígeno del virus del dengue a partir de muestras de sangre. For example, W02007 / 106050 describes an ELISA test to detect flavivirus member-specific antibodies from biological samples, and is based on a competition for epitope binding on the envelope protein of captured flavivirus antigen using Anti-flavivirus IgA in the presence of positive flavivirus serum. For its part, document CN205679623U describes a nitrocellulose fiber covered with colloidal gold and a dengue virus antigen detection kit from blood samples.
Sin embargo, ninguno de los documentos sugiere el uso de una sonda que permita suspender una fibra de manera vertical sin utilizar adhesivos para duplicar el área de contacto en el ensayo. Tampoco anticipan el uso de un arreglo específico de reacción de polimerización por radicales libres, electrospinning y finalmente una impresión 3D o moldeo por inyección para obtener una alta sensibilidad de detección, estabilidad y vida útil del material. However, none of the documents suggest the use of a probe that allows a fiber to be suspended vertically without using adhesives to double the contact area in the test. They also do not anticipate the use of a specific reaction arrangement of free radical polymerization, electrospinning and finally a 3D printing or injection molding to obtain high detection sensitivity, stability and useful life of the material.
Por consecuencia de lo anterior, se ha buscado suprimir los inconvenientes que presentan los ensayos biológicos a base de papel o fibras utilizados en la actualidad, desarrollando un kit y dispositivo cilindrico para la detección de un agente infeccioso que, además de ser estable y realizar un diagnóstico con una alta sensibilidad, permita aumentar el área de contacto de la fibra utilizada, sin utilizar algún adhesivo y reduciendo los costos de operación. OBJETOS DE LA INVENCIÓN As a consequence of the foregoing, it has been sought to eliminate the drawbacks presented by the biological tests based on paper or fibers currently used, developing a kit and cylindrical device for the detection of an infectious agent that, in addition to being stable and performing a Diagnostic with a high sensitivity, allows to increase the contact area of the fiber used, without using any adhesive and reducing operating costs. OBJECTS OF THE INVENTION
Teniendo en cuenta los defectos de la técnica anterior, es un objeto de la presente invención proporcionar un kit para la detección de un agente infeccioso sin utilizar adhesivos con una alta sensibilidad. Taking into account the shortcomings of the prior art, it is an object of the present invention to provide a kit for the detection of an infectious agent without using adhesives with a high sensitivity.
Otro objeto de la presente invención es proporcionar un kit para la detección de un agente infeccioso que utiliza un dispositivo cilindrico para brindar una mayor área de contacto y así reducir los costos de operación. Another object of the present invention is to provide a kit for the detection of an infectious agent that uses a cylindrical device to provide a greater contact area and thus reduce operating costs.
Estos y otros objetos se logran mediante unkit y dispositivo cilindrico para la detección de un agente infeccioso de conformidad con la presente invención.
