The photoelectrochemical detection of salbutamol, which is illicitly used as a lean meat promoter in pigs, is investigated using a molecularly imprinted polymer (MIP)-based sensor with a CuO/g-C₃N₄ nanocomposite to enhance detection performance, leveraging nanomaterials and molecular imprinting for high selectivity and sensitivity. This approach offers a promising strategy for the precise and efficient analysis of salbutamol in food samples.
ความปลอดภัยทางด้านอาหารเป็นหนึ่งปัจจัยที่มีผลสำคัญต่อสุขภาพและการดำเนินชีวิตประจำวัน เนื่องมาจากปัญหาการปนเปื้อนของสารเคมีในอาหารซึ่งก่อให้เกิดปัญหาตามมา อาทิเช่น อาการเจ็บป่วยเล็กน้อย ผลข้างเคียงหรือโรคที่เกี่ยวกับทางเดินอาหาร ไปจนถึงทำให้เสียชีวิตได้ สารซาลบูทามอลเป็นสารที่หาซื้อได้ง่ายเนื่องจากเป็นยาที่ถูกใช้กับผู้ที่เป็นโรคหอบหืดหรือโรคที่เกี่ยวกับระบบหายใจเรื้อรัง โดยสารชนิดนี้ถูกใช้ในทางที่ผิด เช่น การโดปของนักกีฬาหรือเพื่อการเร่งเนื้อแดงในสัตว์ได้

This project aims to design and develop an eye-tracking system to facilitate communication for paralyzed immobile patients. The system is designed to enable patients to convey their needs to caregivers or family members by detecting and tracking eye movements using the Tobii Eye Tracker 5 device. This approach serves as an alternative communication method, replacing the physical movement or speech of paralyzed patients. The system effectively detects and tracks eye movements at a distance of 55 to 85 centimeters and is designed for installation on a computer to ensure ease of use. The program interface consists of three main sections: (1) a set of emotions, (2) a set of needs, and (3) a set of additional needs. It supports input from a virtual keyboard in both Thai and English and allows users to specify additional needs through eye-tracking-enabled typing. Furthermore, the system can generate synthetic speech for text that is difficult to pronounce aloud, send notification messages via the Line application, and store usage data in a database presented in a dashboard format. System testing revealed that the optimal detection distance ranges from 65 to 75 centimeters, as this range yields an error rate of no more than 1 percent. The system accurately responds to eye movements for communication through sound within 3 seconds when interacting with various function buttons. This eye-tracking system effectively enables paralyzed immobile patients to communicate their emotions and needs, facilitating better understanding and interaction between patients and their caregivers or family members.

This research investigates active packaging films made from polyvinyl alcohol (PVA) and nanocellulose fibers (NFC), incorporating silver nanoparticles (AgNPs) synthesized from Terminalia chebula extract, which possesses antibacterial and antifungal properties. The developed films were tested for their mechanical properties, microbial inhibition, and biodegradability. The results showed that the addition of AgNPs from Terminalia chebula enhanced product protection and effectively extended the shelf life of strawberries while being environmentally friendly.

The development of skin-on-a-chip models plays a crucial role in research for drug and cosmetic development. Traditional approaches often utilize two-dimensional (2D) methods that rely on culturing cells on flat surfaces, resulting in a lack of complexity in skin structure and realistic cell interactions. Moreover, traditional methods have limitations in mimicking fluid flow and nutrient circulation, which affects the accuracy of pharmaceutical testing and the prediction of drug effects. This has led to the advancement of three-dimensional (3D) skin models using new microfluidic technology, enhancing the realism of skin structure by replicating both the epidermis and dermis layers, as well as simulating fluid flow similar to physiological conditions in the human body. The design of 3D systems allows for more realistic cell arrangement and interactions, enabling better simulation of skin functions and increasing the accuracy in evaluating the effects of various substances on cell responses, including absorption, inflammation, and wound healing. Therefore, the development of three-dimensional (3D) skin models not only addresses the limitations of traditional methods but also represents a significant step forward in creating models that can be effectively applied in drug testing and pharmaceutical product development.
