Research paper thumbnail of Soft Hydrogel Actuator for Fast Machine-Learning-Assisted Bacteria Detection

Machine learning and robotized bioanalytical platforms require the principles such as hydrogel-based actuators for fast and easy analysis of bioactive analytes. Bacteria are fragile and environmentally sensitive microorganisms that require a special environment to support their lifecycles during analytical tests. Here, we develop a bio-electrochemical platform based on the soft hydrogel/eutectic gallium-indium alloy interface for the detection of Streptococcus thermophilus and Bacillus coagulans bacteria in various mediums. The soft hydrogel-based device is capable to support bacteria' viability during detection time. Current-voltage data are used for multilayer perceptron algorithm training. The multilayer perceptron model is capable of detecting bacterial concentrations in the 104 to 108 cfu/mL range of the culture medium or in the dairy products with high accuracy (94%). Such a fast and easy biodetection is extremely important for food and agriculture industries and biomedical and environmental science.

This work aimed to study the effect of pre‐treatment of vegetable raw materials, namely, ultrasonic processing, and freezing of raw materials under various low‐temperature conditions to obtain multiple types of vegetable milk and determine their characteristics.RESULTSIt is shown that by applying a certain kind of pre‐treatment of vegetable raw materials, it is possible to adjust organoleptic parameters and the content of solids, protein, fat, carbohydrates, fiber, and mineral composition of various types of vegetable milk from soy, rice, oats, wheat, peas, buckwheat, pumpkin seeds, lentils. Ultrasound pre‐treatment allows increasing polyphenol content by an average of 15‐20% for all types of plant milk, except for lentil milk. The results showed that ultrasound treatment for 3 minutes had the most significant effect...

In this regard, the present article aims to review various diffusion approaches used to fabricate different functional materials based on hydrogels, unique examples of materials that control diffusion. They have found applications in fields such as drug encapsulation and delivery, nutrient delivery in agriculture, developing materials for regenerative medicine, and creating stimuli-responsive materials in soft robotics and microrobotics. In addition, mechanisms of release and drug diffusion kinetics as key tools for material design are discussed.

The very sensitive pH-controlled functionality of supramolecular assemblies is a very useful tool for chemical and biochemical implementations. However, the assembly process can be tuned by various factors that can be used for both better functionality control and further functionalization such as active species, e.g., drugs and dyes, and encapsulation. Here, the effect of a dye, sodium fluorescein (uranine) (FL), on the formation of a self-assembled melamine cyanurate (M−CA) structure is investigated and calculated with density functional theory (DFT) and molecular dynamics. Interestingly, the dye greatly affects the self-assembly process at early stages from the formation of dimers, trimers, and tetramer to nucleation control. The supramolecular structure disassembly and subsequent release of trapped dye occurred under both high-and low-pH conditions. This system can be used for time-prolonged bacterial staining and development of supramolecular capsules for the system chemistry approach.

Bacterial strains, including Lactobacillus and Bifidobacterium, are generally used in probiotic food production. However, they are weakly resistant to the stomach's aggressive environment and high temperature, which can result in significant loss of viable probiotic microorganisms. Application of spore-forming bacteria Bacillus coagulans MTCC 5856 allows developing an innovative natural dairy fermented product with high probiotic microorganism viability (p
