Summary
Landscape phages, engineered nanomaterials displayed on phage particles, offer new diagnostic probes and nanomedicines. These phage-based materials enhance biosensors and show promise for targeted cancer therapies.
Area of Science:
- Biotechnology
- Materials Science
- Nanomedicine
Background:
- Phage engineering technology enables the creation of novel phage display libraries.
- These libraries consist of nanofiber materials with diverse molecular landscapes on phage particles, termed 'landscape phages'.
- Landscape phages serve as valuable resources for diagnostic probes and construction materials for biosensors and nanomedicines.
Purpose of the Study:
- To review the development and applications of landscape phage technology.
- To highlight landscape phages as diagnostic/detection probes and construction materials.
- To showcase landscape phage applications in biosensors and targeted nanomedicines.
Main Methods:
- Construction of phage display libraries with diverse molecular landscapes on phage particles.
- Development of high-throughput phage selection methods.
- Engineering of phage-functionalized biosensors and phage-targeted nanomedicines.
Main Results:
- Landscape-phage-derived probes create robust, inexpensive molecular recognition interfaces for mobile detection devices, improving sensitivity and selectivity.
- Phage-programmed nanomedicines, developed using landscape phage technology, demonstrate anticancer efficacy in vitro and in vivo.
- Cancer cell-associated phages and proteins show proficiency in self-assembling into drug- and gene-targeting nanovehicles.
Conclusions:
- Landscape phage technology offers a versatile platform for developing advanced nanomaterials.
- These nanomaterials have significant potential in biosensing, diagnostics, and targeted cancer nanomedicine.
- The review aims to engage chemical scientists and bioengineers in exploring these functionalized nanomaterials.

02:55The Evidence for Evolution
48.3K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

01:54Convergent Evolution
33.0K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

01:24Eukaryotic Evolution
42.1K
The endosymbiont theory is the most widely accepted theory of eukaryotic evolution; however, its progression is still somewhat debated. According to the nucleus-first hypothesis, the ancestral prokaryote first evolved a membrane to enclose DNA and form the nucleus. Conversely, the mitochondria-first hypothesis suggests that the nucleus was formed after endosymbiosis of mitochondria.

3.8K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
