Small molecules (drugs, pesticides, and others) are being consumed directly or indirectly by us in our daily life. Often, these molecules enter the environment and interact with different non-target organisms. Consumption of drugs/pesticides emerged as a major concern for public health, environment, ground-water and agricultural soil. Pesticides can have odd impacts such as degradation of soil properties, environmental pollution, pollution of groundwater as well as the consumption of unwanted drugs can have serious health impacts. Therefore, the sensing of drugs/pesticides plays an important role in detecting and preventing the unwanted usage of drugs/pesticides. Quantitative and qualitative determination of pesticides and drugs can be achieved using electrochemical techniques. This review offers a concise examination of the literature about the electrochemical sensing of drugs and pesticides. The review provides a comprehensive summary of different electrochemical investigations and outlines the reported analytical performance metrics, including limits of detection and linearity ranges. Furthermore, it underscores the progress made in pesticide detection using electrochemical methods for the selected compounds, highlighting the challenges ahead and emphasizing the necessary efforts to develop sensors suitable for in-situ applications.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":13316,"journal":{"name":"Indian Journal of Microbiology","volume":"44 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141170149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-throughput operations can be carefully controlled by using microfluidics and are very cost-effective too. It has been accepted to be a quick and effective method for controlled medication delivery, biological sample preparation, and analysis. This new technology has made it possible to create a wide range of micro and nanocarriers for poorly soluble medications, which has many advantages over traditional drug delivery techniques. Furthermore, a targeted medication delivery system utilizing microfluidic technology can be developed to enhance the drug's local bioavailability. Over the years, extensive R&amp;D in microfluidic technology has led to the creation of various advanced applications in both laboratory and consumer biotechnology. Miniaturized genetic and proteasome analyzers, cell culture and control platforms, biosensors, disease detection, optical imaging devices, diagnostic advanced drugs, drug delivery schemes, and innovative products are some of the advanced applications of the microfluidics system. Also, these are highly adaptable microfluidic tools for disease detection and organ modeling, as well as transduction devices used in biomedical applications to detect biological and chemical changes. Beyond the specialized difficulties in studying cell–cell interactions, microfluidics has several difficulties in biomedical applications, especially for diagnostic devices where minute interactions can lead to imprecise evaluations. Assay function can be significantly changed by the way plastics, adhesives, and other materials interact. Therefore, the foundation of microfluidic technology needs to be grounded in real-world uses that can be produced on a big scale and at a reasonable cost. Further, it is a very interdisciplinary field that requires the collaboration of professionals in fluidics, assay science, materials science, and instrumentation to provide devices with the proper and needed functionality.

This study investigated the immunomodulatory potential of combining Heat-killed Bacillus Calmette-Guérin (hBCG) with a Squalene-based oil-in-Water Emulsion (SWE) adjuvant against TB. The therapeutic efficacy of the hBCG-SWE regimen was assessed in a guinea pig model infected with <i>Mycobacterium tuberculosis</i> (<i>M. tb</i>). Furthermore, the impact of hBCG-SWE on TNF-α and MCP-1 production was evaluated in RAW264.7 macrophages, examining the role of TLR2/4 and MyD88 signaling pathways using ELISA, both with and without specific inhibitors. Our findings revealed that hBCG-SWE significantly enhanced TNF-α and MCP-1 production compared to hBCG alone, indicating activation through TLR2/4 and MyD88-dependent pathways. In guinea pigs, hBCG-SWE administration led to notable reductions in lung pathology and spleen bacterial loads versus control groups. These results highlight the capacity of hBCG-SWE to boost innate immunity and provide robust protection against <i>M. tb</i>.

So, to explore one of the medicinal properties i.e., antianemic potential of cactus pear fruit, the study was planned to assess the effect of lactic fermented cactus pear fruit beverage (LCB) containing <i>Limosilactobacillus fermentum</i> and <i>Lacticaseibacillus rhamnosus</i> on phenylhydrazine (PHZ) induced anemic rats. The anemic model was established with 40 mg/kg PHZ injection for consecutive 2 days. The PHZ injection reduced the heamaglobin from 15 to about 10 g/dL in the experimental animals. LCB was then administered in three doses i.e. 5 mL (T1), 10 mL (T2) and 15 mL (T3) per kg body weight for 14 days with regular diet. Body weight, hematological parameters, creatinine, urea, serum glutamic-oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), fecal microbial count and histology of kidney, liver and spleen of the experimental rats were studied. With the treatment of LCB and standard drug, red blood cells restored to the normal range in T1 (6.31 × 10⁶/µL), T2 (6.28 × 10⁶/µL), T3 (5.81 × 10⁶/µL) and standard control (6.53 × 10⁶/µL) group compared to disease control (4.88 × 10⁶/µL), at the end of study. Hematocrit percentage returned to normal range at the end of study in T1 (42.0%), T2 (42.8%), T3 (38.2%) and standard control (47.9%) as compared to disease control group (32.2%). All the three doses of LCB improved the hematological parameters, restored the level of creatinine, urea, SGPT and SGOT, in blood serum. Further, LCB administered rats’ fecal matter showed significant increase in lactobacilli counts i.e., about rise in 1 log CFU/g on 16th day than 0th day of the study.
