“…This method presents a wide range of applications including biochemical analysis, health diagnostics, food quality control, environmental monitoring and forensic analysis [5][6][7][8]. Colorimetric [9][10][11][12][13][14][15][16], electrochemical [17][18][19], chemiluminescence [20,21], electrochemiluminescence [22], and electrical conductivity [23] detections are main quantifying approaches in the lab-on-paper method although other techniques such as mass spectrometry [24] and surface enhanced Raman spectroscopy [25] have also been applied. Among these methods, colorimetric detection is the most useful method because of its simplicity and easy performance by applying inexpensive and non-sophisticated image analysis software such as Photoshop and also instruments such as a digital camera, scanner or even a mobile phone camera [14,15].…”

“…Polymers are attractive substrates to form flexible devices. Different ways to form flexible sensors [16,17] have been studied for some time. In this paper, polyimide (PI) [18] was utilized to generate laser induced graphene, which is transferred to Kapton tape, forming electrodes.…”

CitationNag A, Mukhopadhyay S, Kosel J (2017) Urinary incontinence monitoring system using laser-induced graphene sensors. 2017 IEEE SENSORS. Abstract-This paper presents the design and development of a sensor patch to be used in a sensing system to deal with the urinary incontinence problem primarily faced by women and elderly people. The sensor patches were developed from laserinduced graphene from low-cost commercial polyimide (PI) polymers. The graphene was manually transferred to a commercial tape, which was used as sensor patch for experimentation. Salt solutions with different concentrations were tested to determine the most sensitive frequency region of the sensor. The results are encouraging to further develop this sensor in a platform for a fully functional urinary incontinence detection system

“…40,41 The development achieved in this area along with new detection systems using colorimetry to electrochemical, chemiluminescence, electrochemiluminescence, fluorescence, and electrical methods has opened avenues for new sensing technologies. 12,34,[42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57] Paper-based microfluidic systems, however, suffer from two major drawbacks: first is the leakage of sample from the rear side of the channels during sample analysis and second is the difficulty in precise incorporation of reagents in the test zone without the inherent spreading of reagents to the surrounding areas including the microchannels. Additionally, covalent immobilization of certain detection reagents (e.g., antibodies, aptamers, enzymes, etc.)…”

This article describes a fabrication process for the generation of a leak proof paper based microfluidic device and a new design strategy for convenient incorporation of externally prepared test zones. Briefly, a negative photolithographic method was used to prepare the device with a partial photoresist layer on the rear of the device to block the leakage of sample. Microscopy and Field Emission Scanning Electron Microscopy data validated the formation of the photoresist layer. The partial layer of photoresist on the device channel limits sample volume to 7 6 0.2 ll as compared to devices without the partial photoresist layer which requires a larger sample volume of 10 6 0.1 ll. The design prototype with a customized external test zone exploits the channel protrusions on the UV exposed photoresist treated paper to bridge the externally applied test zone to the sample and absorbent zones. The partially laminated device with an external test zone has a comparatively low wicking speed of 1.8 6 0.9 mm/min compared to the completely laminated device with an inbuilt test zone (3.3 6 1.2 mm/min) which extends the reaction time between the analyte and reagents. The efficacy of the prepared device was studied with colorimetric assays for the non-specific detection of protein by tetrabromophenol blue, acid/base with phenolphthalein indicator, and specific detection of proteins using the HRP-DAB chemistry. The prepared device has the potential for leak proof detection of analyte, requires low sample volume, involves reduced cost of production ($$0.03, excluding reagent and lamination cost), and enables the integration of customized test zones.
