Photoelectrochemical sensor for salbutamol detection using molecular imprinted-polymer technique with CuO/g-C₃N₄ nanocomposite

Abstract

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.

Objective

ความปลอดภัยทางด้านอาหารเป็นหนึ่งปัจจัยที่มีผลสำคัญต่อสุขภาพและการดำเนินชีวิตประจำวัน เนื่องมาจากปัญหาการปนเปื้อนของสารเคมีในอาหารซึ่งก่อให้เกิดปัญหาตามมา อาทิเช่น อาการเจ็บป่วยเล็กน้อย ผลข้างเคียงหรือโรคที่เกี่ยวกับทางเดินอาหาร ไปจนถึงทำให้เสียชีวิตได้ สารซาลบูทามอลเป็นสารที่หาซื้อได้ง่ายเนื่องจากเป็นยาที่ถูกใช้กับผู้ที่เป็นโรคหอบหืดหรือโรคที่เกี่ยวกับระบบหายใจเรื้อรัง โดยสารชนิดนี้ถูกใช้ในทางที่ผิด เช่น การโดปของนักกีฬาหรือเพื่อการเร่งเนื้อแดงในสัตว์ได้

The use of Houttuynia cordata Thunb and Piper retrofractum Vahl extracts to inhibit opportunistic infections in patient with atopic dermatitis

Atopic dermatitis patients are the second largest number among skin disease patients. There is no cure for atopic dermatitis, and it can only be treated to relieve symptoms, causing chronic disease. There is a chance that opportunistic infections will enter and cause more disease from the patient's wound, causing the patient to have complications from other infections. This study is interested in studying the reduction of the chance of opportunistic infections in patients with atopic dermatitis using natural extracts. The interest is in Plu Kaow and long pepper because there is data supporting the inhibition of microorganisms. The leaves of both plants are crudely extracted, soaked in 95% ethanol for 7 days, filtered with a Buchner filter, and the extracts are tested for phytochemicals to analyze phenolic components, flavonoids, tannins, anthocyanin, DPPH, and tested for antimicrobial properties. The experiments consisted of 5 types of gram-positive and gram-negative bacteria: E. coli, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, and Staphylococcus epidermidis. The researcher expects that this can be further developed and used to treat patients with atopic dermatitis.

Design Electric Tuk-Tuk for the Development of New Automotive Technology

This project aims to design and develop an electric tuk-tuk by converting the traditional combustion engine system to an electric system, supporting the reduction of air pollution and promoting sustainable automotive technology. The electric tuk-tuk is designed using a BLDC electric motor and a control system specifically adapted for the unique driving style of three-wheeled vehicles in Thailand. The study considers suitable energy systems and includes interviews with traditional tuk-tuk drivers to ensure the vehicle meets everyday usability needs. The findings suggest that adopting electric tuk-tuks not only reduces emissions and PM2.5 particulate matter but also enhances an eco-friendly image for Thailand’s tourism sector while supporting domestic innovation and economic growth.

Blood Cell Classification

This project has been developed to address medical challenges related to the process of counting and classifying blood cells from samples, a task that requires both time and high precision. To reduce the workload of medical personnel, the developers have created a platform and an artificial intelligence (AI) system capable of automatically classifying and counting cells from sample images. This system is designed to assist medical laboratory technicians by enabling them to work more efficiently and accurately, reducing the time required for analysis. Furthermore, it promotes the advancement of medical technology, ensuring effective usability from classrooms and laboratories to hospitals.
