Construction and function of photosynthetic oxygen supply system

Composition	Preparation formulation	Function	Ref.
Chlorella	Microneedle	Continuously produce O2	[69]
	Scaffold	Produce sustainable oxygen under light illumination	[54]
Chlorella pyrenoidosa and Panax notoginseng saponins	Scaffold	Produce continuous oxygen, inhibit inflammation, promote angiogenesis and wound healing	[65]
Chlorella pyrenoidosa and Bacillus subtilis	Hydrogel	Continuously produce oxygen and destroy the colonized pathogenic bacteria	[87]
Chlamydomonas reinhardtii	Scaffold	Produce O2 through photosynthesis	[58]
	Hydrogel	Continuously produce oxygen under light and release human VEGF	[88]
	Sutures	Release oxygen and recombinant human growth factors (VEGF, PDGF-BB or SDF-1α)	[52]
Synechococcus elongatus	Hydrogel	Produce O2 through photosynthesis	[53]
	Scaffold	Produce oxygen and lymphangiogenic hyaluronic acid	[89]
Spirulina platensis	Hydrogel	Produce O2 and reactive oxygen species	[61]
