Shopping Without Waste

This thesis started with a wish to improve the world. The waste problem is addressed: it becomes clear that in the Netherlands 10 million tons of waste is generated by consumers 32.9% of this comes from packaging materials and 1.5% comes from plastic waste. Next to that, a person generates 50 kg of food waste on a yearly basis. When wastage in...

A microfluidic AFM cantilever based dispensing and aspiration platform

We present the development of a microfluidic AFM (atomic force microscope) cantilever-based platform to enable the local dispensing and aspiration of liquid with volumes in the pico-to-femtoliter range. The platform consists of a basic AFM measurement system, microfluidic AFM chip, fluidic interface, automated substrate alignment, external...

Development of Nanotools for Applications in (sub-)Femtofluidics and Graphene Technologies

Properties of matter at the nano-scale may be very different from the ones observed at the macro-scale. The continuous variation of characteristics with diminishing size results in relevant changes in behavior. Similarly, these changes are caused by the rise of completely new phenomena (i.e. quantum confinement). Nanoscience can offer an...

Scanning Probe Microscope-Based Fluid Dispensing

Advances in micro and nano fabrication technologies have enabled fabrication of smaller and more sensitive devices for applications not only in solid-state physics but also in medicine and biology. The demand for devices that can precisely transport material, specifically fluids are continuously increasing. Therefore, integration of various...
