“…[ 5 ] The scope of biopolymers is expanding as a result of recent advances in the development of microbial cell factories which can produce diverse bio‐based monomers, thus, most of the polymers can now be regarded as biopolymers. [ 6–12 ] Recently, with the suggestion of environmental life cycle assessments of biopolymer regarding our recent concerns on climate change and resource depletion, drop‐in replacement of monomers based on fossil fuels with biomass‐derived monomer has been exploited for the development of feasible alternatives to conventional synthetic plastics. For example, the Coca‐Cola Company has already been using 30% bio‐based poly(ethylene glycol terephthalate) (bio‐PET) and plans to develop 100% bio‐PET.…”

Advances in scientific technology in the early twentieth century have facilitated the development of synthetic plastics that are lightweight, rigid, and can be easily molded into a desirable shape without changing their material properties. Thus, plastics become ubiquitous and indispensable materials that are used in various manufacturing sectors, including clothing, automotive, medical, and electronic industries. However, strong physical durability and chemical stability of synthetic plastics, most of which are produced from fossil fuels, hinder their complete degradation when they are improperly discarded after use. In addition, accumulated plastic wastes without degradation have caused severe environmental problems, such as microplastics pollution and plastic islands. Thus, the usage and production of plastics is not free from environmental pollution or resource depletion. In order to lessen the impact of climate change and reduce plastic pollution, it is necessary to understand and address the current plastic life cycles. In this review, "sustainable biopolymers" are suggested as a promising solution to the current plastic crisis. The desired properties of sustainable biopolymers and bio-based and bio/chemical hybrid technologies for the development of sustainable biopolymers are mainly discussed.

“…Nowadays, block polymers have been widely used in biomaterials, biosensors and drug delivery for their excellent biocompatibility and high hydrophilicity [23][24][25][26][27][28]. Fluorescent polymers, consisting of polymers and fluorescent molecules, have been extensively developed for their advantages over small molecular fluorescent probes [29][30][31][32].…”

Intracellular pH plays a significant role in all cell activities. Due to their precise imaging capabilities, fluorescent probes have attracted much attention for the investigation of pH-regulated processes. Detecting intracellular pH values with high throughput is critical for cell research and applications. In this work, hybrid semiconducting polymer dots (Pdots) were developed and characterized and were applied for cell imaging and exclusive ratiometric sensing of intracellular pH values. The reported Pdots were prepared by blending a synthesized block polymer (POMF) and a semiconducting polymer poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEHPPV) to construct a fluorescence resonance energy transfer system for ratiometric sensing. Pdots showed many advantages, including high brightness, excellent photostability and biocompatibility, giving the pH probe high sensitivity and good stability. Our results proved the capability of POMF–MEHPPV Pdots for the detection of pH in living cells.
