This makes them an attractive platform for cheap and rapid chemical detection across the globe. Though promising, a major challenge is scaling up biosensor manufacturing to meet the needs of their multiple uses. Currently, cell-free biosensor assembly during lab-scale development is mostly performed manually by the operator, leading to quality control and performance variability issues. Here we explore the use of liquid-handling robotics to manufacture cell-free biosensor reactions. We compare both manual and semiautomated reaction assembly approaches using the Opentrons OT-2 liquid handling platform on two different cell-free gene expression assay systems that constitutively produce colorimetric (LacZ) or fluorescent (GFP) signals.

Although synthetic colorants derived from fossil fuels have been predominantly used due to their low cost, there is a growing need to replace them with natural alternatives. This shift is driven by increasing concerns over the climate crisis caused by excessive fossil fuel use, as well as health issues associated with the consumption of foods, beverages, and cosmetics containing petroleum-derived chemicals. In addition, many natural colorants show health-promoting properties such as antioxidant and antimicrobial activities. Despite such advantages, natural colorants could not be readily commercialized and distributed in the market due to their low stability, limited color spectrum, and low yields from natural resources. To this end, synthetic biology approaches have been developed to efficiently produce natural colorants from renewable resources with high yields. Strategies to diversify natural colorants to produce non-natural derivatives with enhanced properties and an expanded color spectrum have been also developed. In this Review, we discuss the recent synthetic biology strategies developed for enhancing the production of natural colorants and their non-natural derivatives, together with accompanying examples.

Furthermore, comparative transcriptome and chromatin immunoprecipitation sequencing (ChIP-seq) analyses revealed significantly different changes of gene expression by elevated expression of Swr1 and Isw1. Reduced histone H2A.Z occupancy in two key carbon-metabolism regulators of Mig2 and Sip2 was further observed in the engineered yeast.

However, recent outbreaks have revealed neurological complications in adults and severe deformities in newborns, emphasizing the critical need for accurate diagnosis. Lateral flow assays (LFAs) provide a rapid, cost-effective, and user-friendly method for antigen testing at point-of-care, bedside, or in home settings. LFAs utilizing nanobodies have multiple benefits over traditional antibody-based techniques, as nanobodies are much smaller, more stable, and simpler to manufacture. We introduce a nanobody-based LFA for the rapid identification of Zika virus antigens. Starting from two previously reported nanobodies recognizing the Zika nonstructural protein 1 (NS1), we evaluate periplasmic and cytosolic nanobody expression and test different purification tags and immobilization strategies. We quantify nanobody binding kinetics and validate their mutually noncompetitive binding. Avidity effects boost the capture of the tetrameric target protein by 3 orders of magnitude and point to a general strategy for higher sensitivity LFA sensing. The nanobody LFA detects Zika NS1 with a limit of detection ranging from 25 ng/mL in buffer to 1 ng/mL in urine. This nanobody-LFA has the potential to facilitate on-site and self-diagnosis, improve our understanding of Zika infection prevalence, and support public health initiatives in regions affected by Zika virus outbreaks.</p>","PeriodicalId":26,"journal":{"name":"ACS Synthetic Biology","volume":"14 3","pages":"890–900 890–900"},"PeriodicalIF":3.7,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acssynbio.4c00819","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
