Aptamer decorated PDA@magnetic silica microparticles for bacteria purification.

One significant constraint in the advancement of biosensors is the signal-to-noise ratio, which is adversely affected by the presence of interfering factors such as blood in the sample matrix. In the present investigation, a specific aptamer binding was chosen for its affinity, while exhibiting no binding affinity towards non-target bacterial cells. This selective binding property was leveraged to facilitate the production of magnetic microparticles decorated with aptamers.

The Neonatal Intensive Care Unit (NICU) Context and the Perceived Soundscape: A Grounded Theory Approach.

Background: Studies address excessive sound levels and their adverse effects on infants in neonatal intensive care units (NICUs). However, objective measurements represent merely one aspect of the acoustic environment, and investigations into staff's perceptions of the acoustic environment remain scarce in the NICU context. A holistic approach, soundscape, is needed to explore the acoustic environment in-depth.

Striving for wellbeing digitally in the city amidst the pandemic: Solidarity through Twitter in Ankara.

This article elaborates on the utilization of social media for practices of interaction in the city during the COVID-19 pandemic and discusses its potential in providing for the wellbeing of urban communities. During the early periods of the pandemic when preventative measures were taken intensively to decrease contamination, communities lacked physical relationships with and within cities. Interactions realized in physical spaces in normal conditions were compensated with practices in social media.

β-Dispersion of blood during sedimentation.

Aggregation of human red blood cells (RBC) is central to various pathological conditions from bacterial infections to cancer. When left at low shear conditions or at hemostasis, RBCs form aggregates, which resemble stacks of coins, known as 'rouleaux'. We experimentally examined the interfacial dielectric dispersion of aggregating RBCs.

A portable microfluidic platform for rapid determination of microbial load and somatic cell count in milk.

Microfluidics systems that have been emerged in the last 20 years and used for processing the fluid in a microchannel structure at microliter levels are alternative to the conventional methods. The objective of the study is to develop a microfluidic platform for determination of the microbial load and the number of somatic cells in milk. For this purpose, a polydimethylsiloxane (PDMS) chip with a channel size of 300 μm × 60 μm was produced.

Assessment of Lagrangian Modeling of Particle Motion in a Spiral Microchannel for Inertial Microfluidics.

Inertial microfluidics is a promising tool for a label-free particle manipulation for microfluidics technology. It can be utilized for particle separation based on size and shape, as well as focusing of particles. Prediction of particles' trajectories is essential for the design of inertial microfluidic devices.

A Novel, Low-Cost Anesthesia and Injection System for Zebrafish Researchers.

In this study, we designed and developed a novel low-cost system for anesthetizing and injecting adult zebrafish. The system utilizes a gradual cooling method for the anesthesia and maintains the fish in a stable anesthetic plane, as well as stabilizes the animal so that intraperitoneal injections can be consistently performed. It is a system that any laboratory with access to a workshop can build for their group.
