Inkjet Printing and 3D Printing Strategies for Biosensing, Analytical, and Diagnostic Applications

Abstract

Inkjet printing and 3D inkjet printing have found many applications in the fabrication of a great variety of devices, which have been developed with the aim to improve and simplify the design, fabrication, and performance of sensors and analytical platforms. Here, developments of these printing technologies reported during the last 10 years are reviewed and their versatile applicability for the fabrication of improved sensing platforms and analytical and diagnostic sensor systems is demonstrated. Illustrative examples are reviewed in the context of particular advantages provided by inkjet printing technologies. Next to aspects of device printing and fabrication strategies, the utilization of inkjet dispensing, which can be implemented into common analytical tools utilizing customized inkjet printing equipment as well as state‐of‐the‐art consumer inkjet printing devices, is highlighted. This review aims to providing a comprehensive overview of examples integrating inkjet and 3D inkjet printing technologies into device layout fabrication, dosing, and analytical applications to demonstrate the versatile applicability of these technologies, and furthermore, to inspire the utilization of inkjet printing for future developments.

3D Printing as a Technological Strategy for the Personalized Treatment of Wound Healing

“…The main disadvantage is the use of bioinks with low cell density, in order to avoid nozzle clogging and maintain cell viability. The use of inkjet printing can be an important alternative to deliver specific doses of drugs to facilitate wound healing or improve the treatment of other dermatological diseases [ 136 – 138 ].…”

3D-printed fish gelatin scaffolds for cartilage tissue engineering

“…Here, we propose a novel 3D-printed scaffold for cartilage defect repair. Compared with bone tissue engineering scaffolds made using other technologies, cartilage scaffolds prepared by 3D printing have unique advantages in scaffold personalization, accuracy, mechanical strength, pore adjustment, and spatial structure complexity [ [27] , [28] , [29] , [30] , [31] , [32] ]. Current studies have found that 3D-printed cartilage tissue engineering scaffolds also have the advantages of high porosity, uniform pore distribution, high pore connectivity, and compressive strength [ 33 ].…”

Structure, Functionality, Compatibility with Pesticides and Beneficial Microbes, and Potential Applications of a New Delivery System Based on Ink-Jet Technology

“…In addition, a certain amount of water or other easy-to-boil liquid is needed to promote evaporation. Recently, ink-jet printing emerged as the forefront for the biosensor manufacturing approach, including point-of-care diagnostic biosensors [ 13 , 14 ].…”
