T58 |
0-109 |
Sentence |
denotes |
There are various materials that can be used to fabricate lab-on-a-chip devices for DNA or RNA amplification. |
T59 |
110-245 |
Sentence |
denotes |
In the past 15 years, more than ten polymers, ceramic materials, and metals have successfully been used to fabricate such devices [15]. |
T60 |
246-325 |
Sentence |
denotes |
The major property playing a role here is the biocompatibility of the material. |
T61 |
326-414 |
Sentence |
denotes |
The surface of the microfluidic structure should not inhibit the amplification reaction. |
T62 |
415-568 |
Sentence |
denotes |
This biocompatibility can be an intrinsic property of the material or the surface can be modified or coated to achieve this [12,13,14,15,16,17,18,19,20]. |
T63 |
569-699 |
Sentence |
denotes |
One often used material is polydimethylsiloxane (PDMS) [22,23,31,32,34,35,38], which can be processed using soft lithography [39]. |
T64 |
700-817 |
Sentence |
denotes |
However, this is a fabrication technology used in academia and is not suitable for upscaling to mass production [40]. |
T65 |
818-921 |
Sentence |
denotes |
Fabrication methods suitable for mass production are thermoforming/embossing or injection molding [41]. |
T66 |
922-1141 |
Sentence |
denotes |
One of the materials which is biocompatible and suitable for both industrial scale fabrication technologies is cyclic olefin copolymer (COC) [42], which is one of the materials used in the past as well [28,36,43,44,45]. |
T67 |
1142-1322 |
Sentence |
denotes |
Guckenberger et al. estimates the costs of injection molding of only 50 simple microfluidic devices on $47, but this becomes cheaper when the mass production stage is reached [41]. |
T68 |
1323-1396 |
Sentence |
denotes |
Another benefit of COC is the possibility to shape it using micromilling. |
T69 |
1397-1510 |
Sentence |
denotes |
This technique is a rapid prototyping technology and therefore very useful within proof-of-concept projects [41]. |
