Implementing electrically connected metal-coated posts in a Deterministic Lateral Displacement (DLD) device and applying electric fields, we use electrokinetics to achieve tunable particle separations and to trap and manipulate DNA. The strength of DLD stems from its typically binary behavior. Particles move in one out of two trajectories based on their effective size. For particles that are close
We developed the AcouWash (Figures 1 and 2), a benchtop instrument for flow-through cell and particle separation by acoustophoresis. Building on previous research [1-4] AcouWash can re-suspend cells in new medium, separate cells based on size or acoustic properties, or enrich cells, Figure 3. We present our initial evaluation of AcouWash regarding size-based separation of particles, cell washing,
In this paper, a distinctly subjectivist analysis of the nature of relational goodness or goodness for is proposed. Like the generic subjectivist analysis of value, the proposal is to analyse value in terms of attitudes. Specifically, the proposed analysis of goodness for appeals to a special kind of attitude: namely, so-called for-someone’s-sake attitudes. Unlike other analyses in the literature
Structural Health Monitoring (SHM) can provide valuable information for maintenance-related activities and post-disaster emergency management. However, as with any technological system, SHM systems can be susceptible to errors due to malfunctioning. Therefore, it is essential to assess the potential for malfunctions and the associated costs of maintenance and repair when evaluating the long-term b
We present a method based on CRISPR/Cas9 excision and DNA combing to detect anti-microbial resistance (AMR) genes on bacterial plasmids. The assay is inexpensive, simple, fast, and also provides information on the number and size of plasmids in a sample. We demonstrate detection of the gene encoding for the New Delhi metallobeta-lactamase 1 (blaNDM-1) enzyme, known to make bacteria resistant to a
We investigated the impact of inertial forces on acoustic sorting at high sample throughputs. Above a critical flow rate, we observed an unexpected inertia induced breakdown of the sorting efficiency that is not due to the wall induced lift force and was not previously described in the literature. We analyzed the effect experimentally and theoretically, providing an explanation to the phenomena, a
Acquisition of entomological data with high-frequency lidar is an emerging research field in rapid development. The technique offers very high numbers of observations per time unit, suitable for statistical models. In this work, we use a near-infrared Scheimpflug lidar with a sampling frequency of 3.5 kHz to assess the activity of free flying organisms. In-situ measurements were done during the ra
This work presents a novel concept for acoustofluidic cell manipulation: thin vibrating channel walls. Improved etch recipes enable us to produce thin walls between two microfluidic channels, fabricated in silicon or via PDMS casting, that can be used for challenging microbiological applications. We demonstrate the medium exchange for bacteria utilised for transformation, single-cell rotation for
Abstract in UndeterminedSometimes energy security is used as an advocacy for renewable energy systems. Although renewable energy systems can surely have such characteristics they will not per se solve all types of security problems, and new problems will most certainly arise. In this paper, energy security aspects of renewable energy systems are analysed taking the starting point in a broad typolo
Kameraövervakning utgör en pågående trend i kommuners och privatpersoners kamp mot brottslighet. Föremålet för denna rapport är ett särskilt fall som sedan april 2004 ansluter till denna trend: övervakningen av parkeringsplatsen på Kasernplan i centrala Landskrona. Rapporten utgår från statistik, medierapportering, enkätundersökningar samt etnografiskt material (intervjuer och fältanteckningar)
The paper reviews a number of cellular neural network implementations on a field-programmable gate-array. It illustrates experimentally, how these implementations can be used to measure from images or to create dynamic, autonomous processes that facilitate measurements within topographic maps. Applications range from image understanding to robot navigation
