D., Massachusetts Institute of Technology, Department of Chemical Engineering, 2019<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references.<br>The timely diagnosis and treatment of disease in resource-constrained settings requires the development of robust point-of-care (POC) diagnostics, which provide accurate results and can be employed by users with minimal medical training and limited access to basic infrastructure. One of the most common POC diagnostic formats is the immunochromatographic rapid diagnostic test, which traditionally uses nitrocellulose-i

Abstract:

The purpose of this thesis project was to demonstrate the ability to utilize the capabilities of aptamers so that they may act as capture reagents for paper microfluidic devices. Several characterization experiments were conducted as a precursor before the final experimentation was performed. Paper characterization, manufacturing protocols for printing and heating, as well as 3D chip fabrication were all performed and analyzed. The results confirmed that the control of fluid through a 3D microfluidic device based in nitrocellulose is possible. For the biochemistry portion of this thesis rep

Abstract:

This thesis describes methods for improving sensitivity in rapid singleplex and multiplex microarray assays. The assays utilize the optical characteristics of colloidal gold nanoparticles for the colorimetric detection of proteins. Multiplexed detection in sandwich immunoassays is limited by cross-reactivity between different detection antibodies. The cross-reactivity between antibodies can contribute to increased background noise - decreasing the Limit-of-Detection of the assay - or generate false positive signals. Paper I shows improved assay sensitivity in a multiplexed vertical flow assay

Abstract:

Paper (and other cellulose-based materials such as cotton thread and fabrics) are underexploited as materials for the construction of “high-tech” and “lab-on-a-chip” devices. One major drawback of paper is its tendency to absorb water from the environment and, with wetting, to change its mechanical properties; other challenges relate to control over the attachment of molecules (e.g. antibodies, DNA) and cells on its surface, and to the addition of electronic function. The goal of this thesis is to develop paper as a substrate for a range of applications— microfluidics, substrates for electroni

Abstract:

We report on the use of laser direct-write techniques for the fabrication of point-of-care paper-based diagnostic sensors. These include laser-based deposition, laser ablation and laser-induced photo-polymerisation. Firstly, Laser Induced Forward Transfer (LIFT) was employed to deposit biomolecules from a donor film onto paper receivers. Paper was chosen as the ideal receiver because of its inherent properties which make it an efficient and suitable platform for point-of-care diagnostic sensors. Both enzyme-tagged and untagged antibodies were LIFT-printed and their viability was confirmed via

Abstract:

The purpose of this thesis was to demonstrate device functionality of 3-D paper-based, multiplex platforms, µPADs, without the use of coupling agents between layers. Previously, these platforms were fabricated with double-sided tape and cellulose powder to try to augment proper fluid routing, but difficulties with this method occurred. An acrylic housing unit with strategically placed pressure tabs was designed to aid horizontal and vertical fluid routing through the platform, thus eliminating the inconsistencies associated with coupling agents.

Abstract:

N,N′-methylenebisacrylamide-crosslinked poly(N-isopropylacrylamide), also known as P(NIPAM), was developed as a fluid delivery system for use with microfluidic paper-based analytical devices (microPADs). MicroPADs are postage-stamp-sized devices made out of paper that can be used as platforms for low-cost, simple-to-use point-of-care diagnostic assays. P(NIPAM) is a thermally responsive polymer that absorbs aqueous solutions at room temperature and will expel the solutions to microPADs when heated. The fluid delivery characteristics of P(NIPAM) were assessed, and P(NIPAM) was able to deliver m

Abstract:

A funcionalização da matriz celulósica é um ponto essencial para o aprimoramento dos dispositivos microfluídicos baseados em papel (µPADs). Ela permite minimizar o preparo de amostras e a interferência do usuário, principais fontes de erro no processo analítico. A oxidação da celulose durante uma hora com m-periodato de sódio e a imobilização química de enzimas a partir da formação de bases de Schiff (iminas), via a adição direta da enzima ao substrato oxidado sem a necessidade de outras etapas, é um processo rápido e de baixo custo, apresentando grande potencialidade de aplicação nos di

Abstract:

Clinically tractable diagnostics must be low-cost, rapid, sensitive, easy to use, and adaptable to new targets. With its rational design, synthetic biology holds promise for developing diagnostic technologies that can address these needs. In particular, progress in synthetic biology has led to improved circuit-building abilities and a large collection of biomolecular sensors. However, these technologies fundamentally require transcription and translation, limiting their applicability to cellular contexts In vitro cell-free expression systems that contain transcription and translation machiner
