Microalgae have caught the world's attention for its potential to solve one of the world's most pressing issues-sustainable green energy. Compared to biofuels supplied by oil palm, rapeseed, soybean and sugar cane, microalgae alone can be manipulated to generate larger amounts of biodiesel, bioethanol, biohydrogen and biomass in a shorter time. Apart from higher productivity, microalgae can also grow using brackish water on non-arable land, greatly reducing the competition with food and cash crops. Hence, numerous efforts have been put into the commercialisation of microalgae-derived biofuel by both the government and private bodies. This paper serves to review conventional and novel methods for microalgae culture and biomass harvest, as well as recent developments in techniques for microalgal biofuel production.

Radiation therapy is a primary modality for cancer treatment; however, it often leads to various degrees of skin injuries, ranging from mild rashes to severe ulcerations, for which no effective treatments are currently available. In this study, a multifunctional microsphere (PC@CuS-ALG) was synthesized by encapsulating phycocyanin-templated copper sulfide nanoparticles (PC@CuS) within alginate (ALG) using microfluidic technology. Phycocyanin, a natural protein derived from microalgae, shows abilities to scavenge reactive oxygen species, repair radiation-induced damage to skin cells, and ameliorate macrophage-related inflammatory responses.

The widespread use of copper (Cu) in industrial and agricultural settings leads to the accumulation of excess Cu within aquatic ecosystems, posing a threat to organism health. Microalgal bioremediation has emerged as a popular and promising solution to mitigate the risks. Nevertheless, the genetic underpinnings and engineering tactics involved in heavy metal bioremediation by microalgae remain inadequately elucidated.
