The effect of enzyme immobilization on the performance of bio-battery / Muhammad Syafiq Zafran Kamarudzaman

Bio-battery was one of the new fields of energy production that uses carbohydrates or glucose to generate electricity. This type of energy storage device utilizes enzymes to break down glucose into electrons, thus generating a flow of current to produce electricity. One of the major subjects studied...
