Levitation of very small but macroscopic objects is a rapidly developing interrogation technique for nanooptics and optomechanics. Paul traps are one mechanism for levitation of charged particles, which enables interrogation of novel materials or optically active samples in a virtually interaction-free environment, providing a test-bed for completely new experiments. Elementary traps have already been demonstrated for nano- and microparticles as a proof-of-principle for such experiments. We present a linear, segmented Paul trap with a printed-circuit-board-based design for levitation of nano- and microparticles, as a step toward the more sophisticated tools needed for advanced experiments. We describe the trap design, construction, and characterization and address the challenging phenomena associated with such a system. This trap provides a step toward designing an ideal environment for studies using a variety of isolated particles to enable advances in areas including magnetometry, thermodynamics, and optomechanics.

In recent years, nano and micro drug delivery systems targeting the colon have gained more attention due to increasing interest in treating colon diseases such as colorectal cancer and inflammatory bowel disease, , Crohn's disease and ulcerative colitis. Usually, nanocarriers are exploited for their enhanced permeability properties, allowing higher penetration effects and bioavailability, while microcarriers are primarily used for localized and sustained release. In bowel diseases, carriers must go into a delicate environment with a strict balance of gut bacteria (, colon), and natural or biodegradable polymers capable of ensuring lower toxicity are preferred.

Microfluidic fractionation of microplastics, bacteria and microalgae with induced-charge electro-osmotic eddies.

Background: Fractionation of microalgal cells has important applications in producing pharmaceuticals and treating diseases. Multiple types of microalgal cells generally coexist in the oceans or lakes and are easily contaminated by microplastics and bacteria. Therefore, it is of paramount significance to develop an effective fractionation approach for microalgal cells for biological applications.

A novel employment of single particle-inductively coupled plasma-mass spectrometry (SP-ICP-MS) was developed, where a microextraction (ME) probe is used to sample nanoparticles from a surface and analyze them in a single analytical step. The effects of several parameters on the performance of ME-SP-ICP-MS were investigated, including the flow rate, choice of carrier solution, particle size, and the design of the microextraction probe head itself. The optimized ME-SP-ICP-MS technique was used to compare the extraction efficiency (EE, defined as the ratio of particles measured to particles deposited on the surface) of the commercial probe head to a newly designed SP polyether ether ketone (PEEK) probe head.

In nature, nontoxic protein amyloids serve as dynamic, protein-specific depots, exemplified by both bacterial inclusion bodies and secretory granules from the endocrine system. Inspired by these systems, chemically defined and regulatory-compliant artificial protein microgranules have been developed for clinical applications as endocrine-like protein repositories. This has been achieved by exploiting the reversible coordination between histidine residues and divalent cations such as Zn, that promotes protein-protein interactions.

Studies conducted so far have shown that nano- and microplastic may disturb the intestinal microenvironment by interacting with the intestinal epithelium and the gut microbiota. Depending on the research model used, the effect on the microbiome is different-an increase or decrease in selected taxa resulting in the development of dysbiosis. Dysbiosis may be associated with intestinal inflammation, development of mental disorders or diabetes.
