While for the development of cultured meat products, mass production of animal myoblasts is necessary. Both hiPSCs and animal myoblasts consume <span>d</span>-glucose as their energy source and produce <span>l</span>-lactate, which accumulates in cell culture media and inhibits cell proliferation. To make large-scale cell culture economically feasible, <span>l</span>-lactate removal and subsequent reuse of media are of high importance. The adsorption technique is attractive for <span>l</span>-lactate removal due to its low cost, ease of operation, and scalability. The current study is dedicated to 4-(2-hydroxyethyl)-1-piperazineethanesulfonate (HEPES) intercalated Mg–Al layered double hydroxide (LDH), which acts as a biocompatible anion-exchanger in media. HEPES‧Mg–Al LDH was able to remove <span>l</span>-lactate from hiPS cells and myoblast-relevant media selectively while mostly retaining <span>d</span>-glucose. Adsorbent exhibited dose-dependent cytotoxicity to hiPSCs and C2C12 cells, mainly related to elevated osmolarity, HEPES, and Mg levels and adsorption of media micro components. By employing alternatively prepared sol-gel derived HEPES‧Mg–Al LDH, the required adsorbent dose for efficient <span>l</span>-lactate removal was reduced to a safe level. The current study thoroughly evaluates Mg–Al layered double hydroxides as suitable adsorbents for cell culture media regeneration and discusses the limitations of Mg–Al LDHs in systems relevant to hiPS cells and C2C12 cells. This work promotes the cost-effective large-scale production of cells and gives insight into the limitations of Mg–Al LDHs applied to systems of biological origin.</p></div>","PeriodicalId":73541,"journal":{"name":"JCIS open","volume":"12 ","pages":"Article 100099"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666934X23000260/pdfft?md5=21374053ca1363ae2248e82982214ce0&pid=1-s2.0-S2666934X23000260-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138471897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combination of extinction spectra, dynamic light scattering (DLS), and transmission electron microscopy (TEM) measurements reveals the presence of small clusters of AuNPs coated by the antibodies, as well as micron-sized antibody aggregates. Furthermore, static light scattering measurements demonstrate that Ab self-interactions are attractive (with a negative second virial coefficient, B2) and induce very slow Ab self-aggregation over several months.

As stability is directly linked to the size of the dispersed colloids it is essential to assess the size distribution of colloidal suspensions.

However, characterization of colloidal dispersions is usually performed by dynamic light scattering (DLS), that requires static measurements as well as significant volumes, that are not compatible with on-line analysis and microfluidics.

A PDMS microchip, consisting in a millimeter cavity for DLS measurements in parallel with a microchannel, was designed to perform the measurement on the sample without stopping the suspension flow during the microfluidic experiment. The cavity geometry was then optimized thanks to numerical simulation to ensure a good sweep efficiency and to downscale as much as possible without impairing the DLS signal.</p><p>By adapting the microfabrication process, a PDMS microfluidic chip was designed allowing the size measurements of successive suspensions containing 100 and 12 ​nm diameter particles.

Lipid nanocarriers are attractive drug delivery vehicles and these systems can be classified based on their lipid composition into solid lipid nanoparticles (SLNs), nanostructured lipid carriers (NLCs) and nanoemulsions (NEs). In order to develop high drug loading nanoformulations for the treatment of HIV, we investigate the factors that influence the comparative production of SLNs, NLCs and NEs with Imwitor 900k and soybean oil as the solid and liquid lipids respectively. These nanoformulations contained a therapeutically relevant drug mixture of darunavir (DRV) and ritonavir (RTV). We used a simple nanoprecipitation method that does not require any heating of the lipid phase and screened three key formulation factors (lipid concentration, surfactant selection and drug loading) in order to determine their effect on the particle properties and stability of the formulations. Two different surfactants were used, (Brij 78 and Tween 80) which had a significant effect on the ability to form a viable nanodispersion; using Brij 78 as the surfactant resulted in more viable formulations for our lipids. A concentration of the lipid in the organic phase of 4 mg/mL was determined to achieve a good balance between viable formulations and lipid loading resulting in nanoparticles with mean diameters ∼200–300 ​nm. Drug loadings of 10% w/w DRV/total lipid was achieved for SLNs, with loadings of 20% w/w was possible for NLCs and NEs, these values are amongst the highest reported for lipid nanoformulations. All formulations had encapsulation efficiencies of ≥92.5%. Overall, this study shows the versatility of the nanoprecipitation method for producing SLNs, NLCs and NEs.
