Article Abstract

As large-scale planting of genetically modified (GM) crops increases, the development of a rapid and convenient method for on-site detection of GM crops is important. We combined the advantages of recombinase polymerase amplification (RPA) and fluorescence detection to establish a rapid, sensitive, specific, and simple detection platform for on-site detection of MON863 maize. Test samples were added directly to the platform after simple pre-treatment with a DNA extraction-free method. Results were obtained through real-time monitoring with a portable instrument, which facilitated sample-in/answer-out on-site detection. The entire detection process, including sample preparation, RPA and identification of amplification results, was accomplished in approximately 10 min. Furthermore, the detection was achieved with a simple and inexpensive portable device. This method has high potential for application in other fields requiring rapid detection of DNA targets, such as in field research, resource-limited areas, and science education.

A series of molecular logic gates with multiple biocomputing capabilities have been successfully fabricated by using four antibiotic residues [tetracycline (TET), chloramphenicol (CHL), kanamycin (KAN), and streptomycin (STR)] as inputs. The lateral flow strip biosensor was utilized to realize the visual and portable sensing of logic events. Four basic logic gates (OR, AND, XOR, and INHIBIT) and three cascade logic circuits (OR-INHIBIT-AND, 3AND-OR, and XOR-INHIBIT-OR-AND) were constructed.

Background: Hospital admissions occur frequently in nursing homes and are often preventable. Inappropriate hospitalisations due to nursing home-sensitive conditions pose significant risks to residents, place additional strain on emergency departments and hospitals, and thus lead to substantial healthcare costs. In light of demographic changes- characterised by an aging and increasingly multimorbid nursing home population- combined with ubiquitous lack of health care professionals, new strategies are urgently needed to ensure adequate medical care in nursing homes.

Soil erosion is an ongoing environmental problem. To address this issue, calibrated erosion models are used to forecast areas vulnerable to erosion and to determine appropriate preventive measures. Model calibrations are based on erosion data recorded using different techniques such as photogrammetry from an unmanned aerial vehicle (UAV).

Mycotoxins in feed can pose significant risks to the health of livestock and poultry, leading to reduced economic returns and impaired production efficiency, thereby impeding the sustainable development of the livestock industry. Consequently, the exploration of highly sensitive, simple and rapid detection methods for trace mycotoxins in feed is crucial for ensuring feed safety and promoting industrial sustainability. Surface-enhanced Raman spectroscopy (SERS), a rapid detection method characterized by high sensitivity, ease of operation, and resistance to water interference, has gained substantial traction in mycotoxin detection within feed matrices in recent years.
