The microsystem consists of a portable rotary genetic analyzer and a fully integrated lab-on-a-disc device. The portable rotary genetic analyzer is equipped with a couple of heating blocks, a motor and a UV-Vis optical detector. The device was designed with two units: a 3D printed solution-loading cartridge and a centrifugal microfluidic disc. All the essential solutions for the LAMP reaction (a sample, a washing, an elution and a LAMP cocktail solution) are stored inside the cartridge, and orderly released into centrifugal microdevice by a rotation program. Each unit of the device was designed with 20 reaction chambers for simultaneously detecting 19 kinds of food poisoning bacteria in one test. To increase the amount of a sample to 1 mL, we incorporated the super absorbent polymer (SAP) in the waste chamber to absorb the sample and washing solution during the device operation. The whole process was automatically conducted from bead-based DNA extraction to isothermal DNA amplification by LAMP reaction to colorimetric and UV-vis detection of amplicons in 60 min to identify three kinds of bacteria (Escherichia coli O157:H7, Salmonella Typhimurium, and Vibrio parahaemolyticus).","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133767743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the case of the constraint of constant surface area, the passive division can successively take place for 10 times in the situation of Δp = −15 mV; and only 4.5% solution that is contained by the original vesicle with a radius of 4 µm can been retained by 512 vesicles that each contains about 2.31×107 nm3. Thus, if the water channels are embedded in the membrane of vesicle, this method can not only concentrate the solution, but also produce a large number of nanoreactors, which is beneficial to yield an ensemble conclusion of chemical reaction in a very short times. Another case of the constraint of constant volume can also be easy realized by enough supply of the diamagnetic amphiphilic block-copolymers in the progress of division. The latter case is also important for reaction statistics because the original solution can be in equal volume divided into hundreds nanoreactors. This nanoreactor can be used to mimic the reaction of some organelles in vitro. We hope experimenters will try them in future experiments.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129831824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Severe cases of dengue can be fatal, making early detection \u0000and fast diagnosis crucial towards improving patient care and survival rates. Currently, early detection can be \u0000achieved through detection of NS1 protein, using ELISA technique. Unfortunately, ELISA is an expensive \u0000method, making it unsuitable as a screening technique, especially in low-resource settings. In this work, we \u0000present a prototype device and its early validation studies, of an integrated electrochemical and mass-sensor \u0000for dengue NS1 antigen. The sensor is connected to open source mass-sensing software and hardware, \u0000OpenQCM which makes it easily portable. Having dual-measurement capabilities (mass and impedance) \u0000increases the sensitivity of the sensor. Preliminary studies suggest that the prototype could achieve ultralow \u0000limit of detection as low as 10 ng mL-1, dual-sensing cross-validation capability, portable size, sample-toanalysis time of less than 30 minutes, and parallelization of multiple assays.

LOC efficiently carries out all biochemical operations we do in traditional laboratories on a single reconfigurable chip called as Digital Microfluidic Biochip (DMFB). DMFBs helps to achieve parallelism and miniaturization compared to traditional laboratory methods in terms of samples and equipment used. One of the important problem in DMFB synthesis is scheduling. We present a simple method called as Heterogeneous Earliest Finish Time for digital microfluidics (DMHEFT) for scheduling DMFB. It is a greedy heuristic based list scheduling. HEFT is previously used for task scheduling where multiple heterogeneous processors are available for solving inter-dependent tasks depicted as DAG. In this paper, it is applied to Microfluidic biochips. DMHEFT uses Upward rank value to prioritize the tasks or operations and earliest finish time to assign tasks to different modules like mixers, heaters and detectors etc. Simulation results show that it produces better assay lengths and run time compared to existing algorithms.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"259 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122257496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides that, there is no objective methodology for the fulfillment of its functional design specifications. This paper presents an overview of MIRACLE project whose objective is the development and validation of an intelligent system for the design, simulation and flexible manufacture of implant-supported dental prostheses. The developed system in MIRACLE is a CAD/CAM system which allows to test the functional characteristics of dental prostheses considering mandible-maxilla interaction (called occlusion) using virtual models, contrary to most commercial solutions where this test is performed using expensive anatomical replicas tested with mechanical articulators and evaluated with patients. Another objective of MIRACLE is to develop a parametric finite elements model (FEM) of the whole prosthesis in order to analyze the failure risk of dental implants and prostheses before its surgical implantation enabling a re-design process. This paper is focused on the CAD/CAM subsystem developed in order to automatize the process of manufacturing surgical guides using several 3D models of the patient dental anatomy. A summarized version of the image processing step will be also presented. The CAD/CAM subsystem has been clinically validated achieving mean errors less than 5 degrees in the placement of the prosthetic crowns.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132522228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
