Paper-based planar reaction arrays for printed diagnostics

Printing technologies for biomolecule and cell-based applications

“…There is also a small pressure between 50 and 150 N applied when transferring ink to the substrate. Application of flexographic printing for functional materials has mostly concentrated on printed electronics (Tobjörk and Österbacka, 2011) and only few examples exists about the usage of flexographic printing in biological applications, most concerning paper-based diagnostics (Juvonen et al, 2013;Määttänen et al, 2011Määttänen et al, , 2014Olkkonen et al, 2010;Phillips et al, 2012). For example, Phillips et al have shown that pattern arrays of antibodies can be successfully transferred on flexible plastic films and the proteins retain their activity (Phillips et al, 2012).…”

Photothermal effect of gold nanostars inkjet-printed on coated paper substrate under near-infrared irradiation

“…highly-sensitive sensors, tools for immunoassays, and tissue engineering. 3,4 The formulation of suitable inks for deposition of functional materials is considered to be a major factor in the successful application of inkjet printing technologies. Inks made of metal nanoparticles have significant advantages over other formulations, and they are widely used for their relevant conductive and thermal properties.…”

Hyperspectral imaging in quality control of inkjet printed personalised dosage forms

“…The necessity for increased dose-compliance and the need for personalized and accurate drug dosing have led to the exploration of inkjet technology in the field of pharmaceutics (Buanz et al, 2011;Määttänen et al, 2011;Kolakovic et al, 2013;Sandler et al, 2011;Pardeike et al, 2011). Different printing techniques and parameters have been studied to produce flexible dosing.…”
