Nanofibrous spongy microspheres
A nanofibrous spongy microsphere includes porous walls that define an exterior of the microsphere and that extend through an interior of the microsphere. The porous walls consist of interconnected nanofibers and spaces formed between the interconnected nanofibers. A plurality of micro-scale pores are formed throughout the interior of the microsphere. Each of the micro-scale pores i) is partially defined by the porous walls, ii) has an interpore opening that opens to an adjacent micro-scale pores, and iii) has a diameter ranging from about 1 m to about 100 m. A total diameter of the microsphere ranges from about 5 m to about 1000 m.
BLOCK COPOLYMERS AND USES THEREOF
An encoding/decoding apparatus and method using a low-density parity-check code (LDPC code) is disclosed. Basic column group information, serving as a set of information regarding positions of rows with weight 1, is extracted from a reference column in each column group of a predetermined parity-check matrix. Column group information transforms the positions of rows with weight 1 into positions whose lengths are within a required parity length. A parity-check matrix is generated according to the generated column group information. Data is enclosed or decoded based on the generated parity-check matrix.
Lignin-Containing Polymers
Click reactions may be used to bond polymers to lignin by taking advantage of lignin's terminal hydroxyl and thiol groups via an alkyne-azide click reaction or a thiol-alkene or thiol-alkyne click reaction. By selecting functional polymers, these methods may be used to synthesize lignin-containing polymer materials with an array of different properties, such as self-healing polymers.
Biomarker specific amphiphilic nanoparticles
The present invention relates to an amphiphilic nanoparticle specific to a biomarker, and more particularly, provides an amphiphilic nanoparticle which may be used as a diagnosis or treatment-type drug or gene carrier by selectively recognizing a proteolytic enzyme specifically expressed in a cellular membrane of a specific cell, and then being bound to the proteolytic enzyme to efficiently achieve the intracellular uptake and selective cleavage. The amphiphilic nanoparticle of the present invention may be used in the diagnosis or therapy of a disease.
OLIGONUCLEOTIDE DENDRIMERS FOR DYNAMIC AND FUNCTIONAL COLLOIDAL CRYSTAL ENGINEERING
The present disclosure is directed to multicomponent assemblies (e.g., crystalline structures) using oligonucleotide dendrimers and spherical nucleic acids (SNAs). The disclosure also provides methods of forming the multicomponent assemblies.
